Not over yet - a great ball in from Callum Hudson-Odoi asks questions but Michy Batshuayi can't get on it...

Crystal Palace

Crystal Palace midfielder James McCarthy speaking with Sky Sports: "We weren’t at it today. It was disappointing. Not good enough. We went to the champions on Saturday and put in a hell of a performance but tonight we wanted to win the game and push on.

"Unfortunately we were not at the races. We have a lot of injuries. Maybe the boss would have been happy to have made a few changes but no point making excuses.

"Today, each and every one of us didn’t perform. As a squad and a team we know we are a lot better than that."

Tammy Abraham is now down again, prone on the floor.

Chelsea 1-1 Arsenal

Not another injury to an England striker? Tammy Abraham clatters into the advertising screens and that looks painful. It looks horrible in slow motion.

He's back on his feet though...

Brighton & Hove Albion

More from Brighton manager Graham Potter: "We had a few opportunities early-on, then the game turns on its head from five minutes of madness from our point of view. I'm really disappointed with that and that was ultimately the difference in the game.

"He [Aaron Ramsdale] has made a few saves. We were in the game but if you don't defend your box or get that bit of luck then the scoreline goes against you and it's a different complexion on the game.

"That's the challenge. It's my responsibility to do that. There's no shortage of effort. We have to stick together and find solutions. We are disappointed because we were in control for the first 30 mins of the game. We have to learn to be better.

On the transfer window: "We are always active and always looking. Whether we can find the right person to help us is the question. We have to improve the guys we have here around us too."

Good save! Ross Barkley runs on to a clever loft to the back stick and back heads the ball toward the corner, Bernd Leno has to react sharply to get down and push it clear.

Arsenal finally send on Rob Holding, a full 55 minutes after David Luiz was sent off. Off goes Nicolas Pepe. Ten minutes remain.

Newcastle United

Newcastle captain Jamaal Lascelles speaking to Match of the Day: "It's probably one of the weirdest game I’ve been involved in.

"They were the better team but we’ve come back from being two goals down and that shows the spirit and courage in this team. So we’re pleased with that.

"The work ethic carries on throughout all the game. They dropped off and allowed us to play, which benefited us towards the end of the game. We had good subs as well.

"It would be nice to have a cup run but a lot happens in cups and you’ve got to approach it in the right way."

Alexandre Lacazette does well to beat a tackle but then his pass out wide is really poor and easily cut out. Tired legs? They've had 10 men for a very long time now.

Chelsea send on the rarely-spotted Michy Batshuayi.

Brighton & Hove Albion

Brighton boss Graham Potter speaking to BBC Match of the Day: "We played really well for the first 30 minutes. They were struggling to get out of their half. The scoreline has gone against us and then it becomes difficult.

"We pushed and pushed but in the end it's a disappointing evening. The result is the most important thing. There were elements of the performance which was good but we have to learn from that first 40 minutes, not to give too many errors away.

"That's the reality. It's what we have to face. That's the Premier League for you. I have to find the solutions. I believe in the players but we have to act as well. They have been great but we have to try and improve, that includes myself.

"You could focus on the league table or on the job we have to do in the games. You can sit and look at the table but it won't help them. We have to improve the things we need to do better."

Tammy Abraham flicks a header tamely at Bernd Leno. Chelsea look a bit leggy and short of ideas out there.

Manchester City

Manchester City right-back Kyle Walker: "It says a lot about this club, where they are in the league, they set up well and we found them hard to break down.

"It's always good to come back here, I come back and watch when I can but it was important to bounce back from the weekend. I'm grateful for the three points and the clean sheet.

"Aymeric [Laporte] is a great player, he's proved that since he came here. This year we need to look at ourselves as a team, rather than individually."

Karen Carney
Former England winger on BBC Radio 5 Live

That young lad earned that luck. Martinelli has worked his socks off in defence and attack tonight - he has been superb. The grit that Arsenal have needed over the last couple of years - he has got that. He is going to be a big, big player.

Southampton

Ralph Hasenhüttl speaking with BBC Match of the Day: "I think it was one of our best performances of the season. It's not so easy to win here. Especially with the ball in the first half, we were absolutely fantastic - very flexible and hard to defend against.

"We created a lot of chances but it was only 1-0 at half-time. In the second half it was important that we did not make the same mistakes as we did against Wolves but we were very clinical and came up with a beautiful goal from Stuey.

On the performance of goalscorer Nathan Redmond: "Nathan gave by far his best performance of this season. In that form, at number 10, he is our most important player.

"He had a difficult time at the start of the season, when like the rest of the team he was struggling, but the turnaround has been fantastic.

On the change in the team's fortunes: "Throughout the team - the behaviour, belief - everyone is absolutely committed. They know what they have to do and the atmosphere is fantastic. Everyone enjoys to play."

Chelsea now do start to pose a threat. Willian hits a shot which is beaten away at the near post by Bern Leno before a cross from the right is nodded back and Tammy Abraham is nearly on to it.

Granit Xhaka then clears his lines well at the front post. Have we found his position?

Into the last 15.

Arsenal have suddenly started playing, looking slick and dangerous now. Alexandre Lacazette is played in and buries it but he's well offside. Chelsea slow and ponderous since half time.

Bournemouth

Bournemouth keeper Aaron Ramsdale on his impressive performance: "The first save is probably the best save of the lot. If we had gone 1-0 down our heads might have dropped so to keep the score at 0-0 was most crucial.

"I could see them [Brighton] getting frustrated but it was probably our best performance of the season. I'm surprised you can't hear the celebrations! [of his team-mates in the dressing room].

"We need to back this win up. We have Arsenal in the FA Cup then a massive game against Aston Villa next week."

Manchester City

Manchester City manager Pep Guardiola talking to Match of the Day: "We knew it would be a difficult place to come. We concede one or two clear chances, nothing more than that. In the first half the keeper was excellent with the penalty and two incredible saves, it was an incredibly good victory for us to take a step towards securing Champions League football next season.

"In the first half we were a little bit shy to play, but in the second half we were a little bit more like we are. But we controlled it really well, the chance to score goals.

"What Sheffield United do, they do it perfectly. They’ve been together for five years so their spirit is so good. They are so good at the second balls and arrive with a lot of people in the final third."

N'Golo Kante's slip has changed this game and he's now brought off - on goes Mason Mount as Frank Lampard looks to drive home the one-man advantage.
