Yuzuru Hanyu second after combo error, with figure skating pairs world champions Sui Wenjing and Han Cong taking narrow lead in Turin
We're closing up the live blog now but you can find a full report with further reaction after the men's short program plus details of the pairs short program here.
Hope you've enjoyed keeping up to date with the action from Turin. But there's no time for slacking with two days still to go and Alexandra Trusova and Olympic champion Alina Zagitova getting their campaigns underway tomorrow.
There's also the conclusion of the junior ladies' event with Alysa Liu leading a posse of Russians after landing a triple Axel in her short program.
Join us tomorrow to find out. The live blog for Day 2 (Friday 6th December) is here.
All times below are Central European Time/CET (UTC +1 hours). Most recent posts appear first. Please refresh the page for latest updates.
He may have achieved a personal best in the short program, but Nathan Chen insists there is room for improvement.
"Perfection is something that I don't think anyone can really obtain. But I'm happy with the Lutz. The second two jumps were a little shaky. I would definitely like to make those a little lighter, since I know I'm capable of doing that. And the program I think I can definitely start feeling the music better.
"Overall though, I'm pretty satisfied with the program and I'll sit down and watch the program and see what I can improve on."
A new costume attracted plenty of attention with Chen grateful to designer Vera Wang for getting it made.
"I saw Vera before I came here, and she gave me a whole bunch of different costume ideas. We'll play around with it this season but this is something... thankfully to her, very quickly done. It was really comfortable. I wanted something that was comfortable.
"The other shirt is a little bit heavy and I don't feel like I'm very free in it, I feel really restricted. So that was a big deal for me."
As for the pressure of defending his Grand Prix Final title, Chen said, "I mean, I just try to have fun with it. I can't go to every single final so the fact that I'm here is a huge honour so I'm just happy to be here and so that's what I'm focussing on."
Speaking in the press conference after skating, he added, "It's such a pleasure to skate here with Yuzu and of course, Kevin [Aymoz]. Happy to be here.”
The double Olympic champion was all alone in the 'kiss and cry' with coaches Brian Orser and Ghislain Briand not in Turin.
When asked about it, Hanyu replied, "It didn’t bother me that my coaches were not with me. They both had difficulty with accreditation and getting into the country."
Hanyu's skate was going perfectly until he stepped out of a quad toe loop leaving him unable to add the triple toe loop in the combination.
He said, "This program was performed by Johnny Weir in Turin in the  Olympics. I feel disappointed I didn’t perform at my best.
"The number of points between me and Nathan is pretty big so it will be difficult to come back."
The action may be over but we're getting reaction from the protagonists on the first day proper of the 2019 Grand Prix of Figure Skating Final in Turin.
In their first meeting since the American retained his world title in Saitama in March, Chen produced the second best short program in history to take a 12-point lead into Saturday's free skate.
That missed combo proved costly for Yuzuru Hanyu but he goes into second place thanks to a score of 97.43, just 0.72 ahead of Kevin Aymoz.
Hanyu was all alone in the kiss and cry with coaches Brian Orser and Ghislain Briand still not sighted in Turin.
It was all looking so good for Yuzuru Hanyu.
A flawless quad Salchow was followed by an equally impeccable triple Axel, but he got the first part of his quad toe loop-triple toe loop combination all wrong and was unable to start the second half.
He cannot beat Chen with that, and he might struggle to overtake Aymoz. Just awaiting the score now.
Still no sign of Yuzuru Hanyu's coaches, Brian Orser and Ghislain Briand, as Japan's double Olympic champion takes to the ice to screams of adulation inside the Palavela.
He follows Alexander Samarin who made a number of jumping errors on his way to a score of 81.32 and fourth place for now.
Wow! Nathan Chen has laid down the challenge to Yuzuru Hanyu in no uncertain fashion with a quite superb short program.
Hanyu's fans may be here in abundance, but even they were applauding the American who landed all of his jumps - a quad Lutz, a triple Axel and a quad toe loop-triple toe loop combination - with great authority.
He skated with great feeling as well to 'La Boheme' and was rewarded with a personal best of 110.38, just 0.15 behind Hanyu's world record set at last year's Rostelecom Cup.
Dmitri Aliev opened with a quad Lutz-double toe loop combination instead of a quad Lutz-triple toe combo.
He then looked to be going along nicely with a quad toe loop a triple Axel although he then almost came unstuck on the step sequence.
It was a good skate but not enough to displace Aymoz from top spot, scoring 88.78 to go second for now with double world champion Nathan Chen next to skate.
Jin Boyang made the worst possible start to his Grand Prix Final, getting his opening quad Lutz all wrong.
The Chinese showed guts to bounce back, landing a quad toe loop-triple toe loop and a triple Axel, but that early error will cost him at least 10 points.
The score is in - 80.67 - which leaves him with a mountain to climb if he is going to make the podium.
In his first Grand Prix Final, Kevin Aymoz was all ready to skate to Prince's 'The Question of U' but the wrong music came on. Twice.
Did it bother him? Not in the slightest. If anything, it fired him up.
He landed his quad toe loop, more solidly than previously this season, followed by a triple Lutz-triple toe loop combination and then a triple Axel.
Throw in his trademark artistry and you have a wonderful performance to start this final with the crowd giving him a huge ovation afterwards.
The result was a score of 96.71, almost two points better than his previous personal best, accompanied by a scream of delight from the Frenchman who insists skating is all about having fun.
Yuzuru Hanyu certainly won't lack for support here in Turin with plenty of fans dressed up as Pooh Bear.
The Japanese has had his favourite Pooh tissue box for company in practice, but there's been no sign of his coaches Brian Orser and Ghislain Briand inside the Palavela so far.
We believe there have been flight delays but we'll keep an eye out for Hanyu's support staff.
There was just a huge cheer as Hanyu's face flashed up on the screen and now the six men's finalists are on the ice for the warm-up. Here's the order:
Kevin Aymoz (FRA), Jin Boyang (CHN), Dmitri Aliev (RUS), Nathan Chen (USA), Alexander Samarin (RUS), Yuzuru Hanyu (JPN)
How often do flaws in the warm-up show up in the performance itself?
Sui Wenjing and Han Cong were far from perfect on their throw triple flip in the warm-up, and Sui had a hand down in the routine proper.
That setback did not affect them in the slightest with a triple twist lift performed expertly just moments later.
It looked like it would be close between them and Aleksandra Boikova and Dmitrii Koslovskii for the lead, and a score of 77.50 was enough to give the world champions the advantage by just 0.85 points.
Daria Pavliuchenko and Denis Khodykin are in third place on 75.16 with another Russian pair, Anastasia Mishina and Aleksandr Galliamov, fourth on 71.48.
Aleksandra Boikova and Dmitrii Koslovskii still lead after a disappointing short program from Peng Cheng and Jin Yang.
The Chinese struggled on their synchronised triple toe loops and Peng had a foot down on the throw triple loop.
Their score of 69.67 leaves them down in fourth.
Boikova and Koslovskii have just spoken to reporters and said, "It wasn’t our worst or best skate. It wasn’t the skate of our lives, so we have a lot to work on."
Their main rivals here in Turin are world champions Sui Wenjing and Han Cong, and they said, "They are very experienced skaters we admire. They have an amazing choreographer, Lori Nichol, and she does an amazing job."
Turin is, of course, the home of Italian football giants Juventus who boast Cristiano Ronaldo in their ranks.
When asked if he'd like the Portuguese star to come and watch, Koslovskii said, "Yeah, we called each other and arranged it."
Yuzuru Hanyu has just been sighted on the big screen getting his arms nice and loose ahead of the men's short program in around 45 minutes. And the crowd are loving it!
A few nervous moments for fans of Sui Wenjing and Han Cong as their throw triple flip in the warm-up didn't quite go to plan with Sui raising her head to the heavens afterwards.
They do not have a great deal of room for error with Aleksandra Boikova and Dmitrii Koslovskii in the lead on 76.65.
Peng Cheng and Jin Yang are just about to start their short program.
Based on what we've seen so far this season, Aleksandra Boikova and Dmitrii Koslovskii look to be the biggest threats to world champions Sui Wenjing and Han Cong here in Turin.
And the Russian pairs duo did not disappoint, skating to a string version of 'My Way'.
A couple of elements - side-by-side triple Salchows and a triple twist lift - were cleared after review and their score of 76.65 puts them into the lead.
The second warm-up group is now on the ice with Sui and Han last to go.
If the first two performances in this pairs' short program are anything to go by, this is going to be a fantastic night.
Daria Pavliuchenko and Denis Khodykin have just produced a super skate including a spectacular throw triple loop and wonderful synchronicity on their jumps and spins.
Their score of 75.16 is just down on their season's best, but it's enough for the lead and puts them well in contention for a podium finish.
Anastasia Mishina and Aleksandr Galliamov have made a fine start to the first senior event of this 2019 ISU Grand Prix Final.
The world junior champions opened in style with a triple twist lift, a throw triple flip and then superb synchronised triple Salchows.
There were a couple of ragged elements after that, but the Russians put in a good performance and scored 71.48, three points down on their personal best set at October's Finlandia Trophy.
The opening ceremony is over. No Shizuka Arakawa but hopefully we'll see her perform in Sunday's gala.
Now we're getting ready for the first senior competition of the week, the pairs short program.
This looks set to be a duel between China's world champions Sui Wenjing and Han Cong, and Russian duo Aleksandra Boikova and Dmitrii Koslovskii who also won both their Grand Prix assignments.
Warm-Up Group 1

Matteo Rizzo is currently on the ice skating to the Bee Gees' 'Staying Alive' as part of the opening ceremony of the Grand Prix Final.
The European bronze medallist missed out on the competition after finishing sixth at Skate Canada and third in the Cup of China.
Italian skaters appear to be to the fore although Shizuka Arakawa, the ladies' singles gold medallist from the 2006 Olympics held in this arena, was sighted earlier and could make an appearance.
Kamila Valieva was only fourth in the junior ladies' short program despite boasting the season's best score.
The 13-year-old has been back in training for just a few weeks after injury, but said her performance was "just down to nerves".
She also refused to be drawn on whether she would attempt the planned quad toe loop in the free skate.
Her training partner Daria Usacheva is second, just over a point behind leader Alysa Liu.
She told Olympic Channel she was able to perform well due to increased confidence saying, "Throughout stages of the Grand Prix series I was nervous before making a jump. And currently I don’t have this fear. I am calmly doing my elements."
With Valieva known for her quad jumps, Usacheva - the younger of the two by a month - has been in her shadow to an extent.
Usacheva is looking to add a triple Axel to her repertoire and says of their relationship, "I've known Kamila for a long time. We are friends, we train in the same group. I don’t worry about opinions over who is better and who is worse."
Alysa Liu spoke to reporters after beating the Russian quartet to take the junior ladies' short program.
She said, "I was very happy with how I skated. I honestly just wanted to come here and do my best, and so far - in the short program - I have done my best so far and I'm very happy with it. Obviously I can improve in everything but I'm happy right now."
The 14-year-old has two quad Lutzes planned for her free skate on Saturday.
She says a quad Salchow is next on her list and added, "I want to get all the quads someday but right now I'm also focussing on skating skills because I really want to improve that."
Liu takes inspiration from Nathan Chen and Alexandra Trusova who she says is "really brave and goes for everything and she's very strong."
On maintaining a balance between her high-difficulty elements and her physical wellbeing, the US national champion said, "If I feel tired I stop. I do a lot of off-ice training so I build strength so I won’t injure myself. So I have to maintain and keep up with my off-ice training so that on-ice it’s harder to get injured."
And her dream?
"My dream is to go to the Olympics and compete there."
Six high-quality skates in the junior ladies' short program and very little to choose between the field.
Alysa Liu leads after landing a triple Axel-triple toe loop combination at the start of her routine, but her score of 71.19 - a new ISU personal best - leaves her just a point clear of the chasing pack headed by Russia's Daria Usacheva.
Kseniia Sinitsyna is third on 69.40 ahead of Kamila Valieva on 69.02.
The fourth Russian, Viktoria Vasilieva, is fifth thanks to a personal best of 68.07 with Korea's Haein Lee sixth but still in contention on 65.39.
There was a lot riding on the first element of Alysa Liu's short program, a triple Axel-triple toe loop combination.
And the US national champion nailed it before landing a double Axel and a triple loop, and receiving a big ovation from the Turin crowd.
She scored 71.19, a new ISU personal best by almost two points but over two points shy of her short program score when she won the US nationals in January.
Daria Usacheva is second on 70.15 after a clean skate with training partner Kamila Valieva just behind on 69.02.
Kamila Valieva was first to go in the junior ladies' short program.
It wasn't her best skate with the 13-year-old marked down as she came close to the boards on her opening triple loop.
But her double Axel and triple Lutz-triple toe loop combination were both well executed as she scored 69.02, over four points down on her season's best.
Training partner Daria Usacheva is next to go followed by Alysa Liu.
Apollinariia Panfilova and Dmitry Rylov may be leading after the junior pairs short programs, but overall victory is far from their minds.
Speaking to Olympic Channel afterwards, they said, "We know that if we skate well we can definitely compete for one of the podium places."
Among their planned elements in the free skate is a high-difficulty synchronised triple Salchow.
When asked about it, they replied, "We will have to see, can we not comment on this?"
The six competitors in the junior ladies event are on the ice ahead of the short program. They go in the following order:
Kamila Valieva (RUS), Daria Usacheva (RUS), Alysa Liu (USA), Viktoria Vasilieva (RUS), Kseniia Sinitsyna (RUS), Haein Lee (KOR).
While US national champion Alysa Liu is the best known in the field, Kamila Valieva has posted the best score in the Junior Grand Prix this season with the 13-year-old, who trains with Alina Zagitova and 'the 3As' under Eteri Tutberidze in Moscow, the favourite.
Both Liu and Valieva have landed quads in competition and we should see them in tomorrow's free skate.
Liu is the only skater to attempt a triple Axel in this upcoming short program.
Russia are dominating the juniors pairs with Apollinariia Panfilova and Dmitry Rylov in front after the short program.
The pair were last to go and, unsurprisingly, looked a bit nervous in the biggest event of their young lives so far.
But they managed to achieve high scores for their elements including a fine triple twist lift early on in their skate to music from The Matrix to post 68.60, more than two points ahead of Kseniia Akhanteva and Valerii Kolesov.
It's close for third with Diana Mukhametzianova and Ilya Mironov scoring 64.90, just ahead of Alina Pepeleva and Roman Pleshkov on 64.67 and Iuliia Artemeva and Mikhail Nazarychev on 63.89.
Germany's Annika Hocke and Robert Kunkel, the only non-Russian pair in the line-up, are sixth on 59.47.
The second group of pairs teams are warming up on the ice and it already looks as though Russia will sweep the medal berths.
Diana Mukhametzianova and Ilya Mironov currently lead on 64.90 with Iuliia Artemeva and Mikhail Nazarychev just 0.99 points behind.
Germany's Annika Hocke and Robert Kunkel, the only non-Russian pair in the line-up, are third on 59.47.
There was disappointment for the home crowd earlier as Daniel Grassl, the only Italian competing on home ice at the Grand Prix Final, finished fifth in the junior men's short program.
Grassl beat Matteo Rizzo 12 months ago to become national champion before finishing sixth at January's European Championships where Rizzo took bronze.
The 17-year-old spoke to Olympic Channel yesterday and told us about his plans to land a quintuple jump in the future!
A Russian medal sweep looks likely in the junior pairs with five duos from that country in the line-up.
The only non-Russian pair is Annika Hocke and Robert Kunkel who are Germany's first representatives in a Junior Grand Prix pairs final.
They were first to go and scored 59.47 which will probably leave them out of the podium places overnight.
Andrei Mozalev has just spoken to Olympic Channel after taking a lead of nearly five points into Saturday's free skate.
The 16-year-old from St Petersburg said, "It’s interesting to be the leader. But on the other hand, it doesn’t make much difference if I am second or third. I am just setting my mind to do my program well.
"I don’t think about my rivals, I think about myself."
Andrei Mozalev takes victory in the junior men's short program with an excellent clean skate.
The last of the three Russians in the six-strong field landed a triple loop, a triple Axel and a triple Lutz-triple toe loop combination to score 82.45 and overtake long-time leader Daniil Samsonov.
It's fair to say the occasion got to some of the youngsters with four of the six coming unstuck on jumps.
Samsonov, the youngest in the field at 14, spoke to Olympic Channel after his skate.
He fell on his opening triple Axel and said, "I am not very satisfied with my skate. I could have done better."
On the rivalry between the Russians and the Japanese, he said, "I try not to focus on it and just make sure I skate my program clean. The coaches usually tell me to watch my mistakes."
Shun Sato was third ahead of Petr Gummenik and home favourite Daniel Grassl - who singled a triple loop in his skate - with Yuma Kagiyama down in sixth.
It's all to play for in the free skate with just 11 points separating the field, and Kagiyama has already shown this season that he is definitely not out of the race for gold.
Daniil Samsonov is still in the lead with just two to go in the junior men short program.
Shun Sato was just 0.5 behind his score of 77.75 after a couple of suspect spins despite landing his jumps - including a triple Axel - well.
Yuma Kagiyama, the son of two-time Olympian Masakazu Kagiyama, also had trouble on his opening jump as he popped his triple Axel into a downgraded double.
The runaway winner of last month's Japan junior nationals is currently down in fourth place on 71.19 after Petr Gumennik moved above him with 72.16.
Now it's the turn of home favourite, Italian national champion Daniel Grassl.
It's never easy being the first skater out, and 14-year-old Danill Samsonov, coached by Eteri Tutberidze, fell on his opening triple Axel.
But the rest of his routine was pretty solid with some excellent spins. His score of 77.75, some 10 points down on his best, is the mark to beat.
He might not stay in the lead for very long with Shun Sato nailing his opening triple Axel and putting together an excellent skate.
The six junior men are on the ice for the warm-up ahead of their short program. And here's the order they will go in:
Daniil Samsonov (RUS), Shun Sato (JPN), Yuma Kagiyama (JPN), Petr Gumennik (RUS), Daniel Grassl (ITA), Andrei Mozalev (RUS).
Meanwhile, we've just grabbed a quick word with defending ladies' champion Rika Kihira.
The Japanese won last year's Grand Prix Final in her first senior season, but she's had to watch the three Russian youngsters sweep all before them in the current series.
And she's merely concentrating on her own performance, saying, "I will do my best to do my competition without making any mistakes. I think it is the most important thing."
He may not be competing but we ran into Italian skater Matteo Rizzo at the Palavela. The European bronze medallist and Universiade winner said: "I'm really looking forward to seeing everyone here and I've come to support all of my friends."
Italian national champion Daniel Grassl is in action on home soil in the Junior Grand Prix men's competition.
So practice is over which means competition will be underway very shortly!
There was a fair bit to unpack from that ladies practice, with Anna Shcherbakova also introducing the quad flip to her free skate run through but falling. Could we see three quads from the 15-year-old on Saturday?
She may not be jumping quads or triple Axels, but it was a clean free program run through for Olympic champion Alina Zagitova, while first-placed qualifier Alena Kostornaia made a couple of errors in hers, including a step out on her opening triple Axel.
She's known as the 'quad queen' but it looks like Alexandra Trusova now has another weapon in her armoury.
The 15-year-old jumped the triple Axel during her opening practice session at the Grand Prix Final, despite the jump not being listed in her planned program content.
Last month her coach, Tutberidze, posted a video to Instagram of the youngster training the notoriously difficult triple jump.
As well as the 3A, the teen also jumped the quad flip during the session, meaning we could see a quad-fest from the Russian in Saturday's free skate. She already jumps the quad Lutz, Salchow and toeloop.
There are four Russian finalists in the women's field - all trained by Eteri Tutberidze - and yesterday none of them were present for the first practice session as they continued training at home in Moscow instead.
Today it's a full house in practice as Olympic champion Alina Zagitova and talented newcomers Alexandra Trusova, Alena Kostornaia and Anna Shcherbakova - nicknamed the 3A - take the ice.
They join Japanese Rika Kihira and Bradie Tennell of the USA.
There's only a scattered crowd in the Palavela at the moment but there were still cheers and whoops for world champions Papadakis and Cizeron following their free dance run through.
The French currently hold the world-leading scores for rhythm dance, free dance and overall - all set at NHK Trophy a couple of weeks ago. Will we see them reach even greater heights here in Turin?!
They'll be channeling Lady Gaga and Bradley Cooper with a run through of their free dance in this session, skating to music from 'A Star Is Born'.
Having missed last year's event due to a back injury for Cizeron, the French duo have been peerless ever since and rewrote the record books at the NHK Trophy a fortnight ago.
We saw their 80s-inspired Fame rhythm dance routine in practice yesterday and could get a run through of their free dance in this session.
The fans have been decorating the Turin Palavela arena with banners supporting their favourite skaters. Who are you cheering for? Let us know on social media @OlympicChannel.
Coach Eteri Tutberidze is one of the busiest women in Turin this week, bringing multiple skaters to Turin, including Olympic champion Alina Zagitova and quad-jumping prodigy Alexandra Trusova.
The renowned coach's daughter, Diana Davis, is also competing in the Junior Grand Prix Final. The 16-year-old Russian and her partner, Gleb Smolkin, have just been on the ice in the junior ice dance practice.
Hanyu hinted once again that we could be seeing his quad Lutz in this competition as he landed the jump again outside of his run through. The double Olympic champion also landed it in practice yesterday.
He fell attempting the same jump in practice at NHK Trophy 2017, causing a serious ankle injury, but it seems well and truly back in his plans.
Skating to 'La Boheme', USA's Chen posted a clean run through of his short program, jumping a quad Lutz, triple Axel and a quad toeloop, triple toeloop combination.
In a run-through of his short program, 'Otonal', Hanyu landed a quad Salchow and triple Axel but took a tumble on an attempted quad toe loop. The Japanese skater then added the quad, in a clean combination with the triple toe, at the end of his run through, much to the delight of the watching fans.
No sign of Yuzuru Hanyu's coach Brian Orser or jumping coach Ghislain Briand at the boards this morning. Just Hanyu's trusty mascot, his Winnie the Pooh tissue box.
Earlier the senior pairs took the ice for their final practice ahead of the short program later, 19:50 local time (18:50 UTC).
In the stands to see some of the action was reigning men's world champion Nathan Chen, who caught some of Sui and Han's routine ahead of his own practice.
