The Premier League returns with four more fixtures tomorrow night, including the Merseyside derby. See you then!

Arsenal

Arsenal manager Mikel Arteta to BBC Match of the Day: "I'm really happy with the performance, collectively and individually. To stand up in a big match against a big opponent and to get a result with the performance that we had today, makes me really pleased.

"From the beginning we looked really sharp, really active, sharp, aggressive off the ball.

"I have analysed every game from them [Chelsea] and they have been outstanding. They have played some big teams and were better than them, they've deserved better results. I think they are a great team. They are extremely well-coached with good individuals. Credit to our players, they've done really well today.

"The energy, the belief in the team, every time we had the opportunity to go forward we did."

On Kai Havertz: "His overall contribution in every phase of play was tremendous. When you add the two goals he scored and some of the link-up play that he had in big moments, [it was] a great performance.

"Individually we had some great performances. We have to do our job. Now we have to wait and see [for Liverpool and Manchester City's results]."

Chelsea

Chelsea captain Conor Gallagher on a young Chelsea supporter holding up a sign questioning the players' efforts at Arsenal: "We definitely are putting the effort in. I know how much it means to all the boys. It is a very young squad with not much experience as a team in the Premier League.

"We have had a lot of ups and downs and we are still improving as a team to get to the next level and today was one of those days we were nowhere near it. But also we will look at the performance and where we can improve and move forward."

Victor: The only way to solve Chelsea problems is to sack Poch and bring in either Jose Mourinho or Antonio Conte.

Ultimately, Chelsea are eight points better off this year than they were at the same stage last season.

If you buy all potential [it's difficult]. You can say we will buy a 21-year-old for £20m and they will be worth £80m in a few years' time. It doesn't quite work like that.

You can have really talented player and they lose themselves.

Chelsea

Chelsea manager Mauricio Pochettino speaking to TNT Sports about whether Cole Palmer was the reason they lost at Arsenal: "We cannot say that was the reason we lose the game but we lose a player who is a creative player who helps to link the team. We are losing players an that is made very difficult, the management. But I think today, more than that, it was difficult to be in the game.

"Where Arsenal are is where we need to be as well. We are talking too much this season and all the information we receive now is that we want to be in a different position next season."

On Chelsea's European prospects: "Now it is difficult to see the future because after this game we feel disappointed. It is difficult to talk about objectives. If we compete like Saturday, OK. But if we compete like today, I think we deserve to go into Europe? I think in this way, no."

Chelsea

Chelsea manager Mauricio Pochettino to BBC Match of the Day: "It's not difficult to explain. Everyone saw we didn't compete from the beginning of the game. After we concede I think the team was so soft. I'm so disappointed with the start because we're supposed to have full energy and compete better.

"We were not aggressive and we did not concentrate in situations where it is easy to find the solution. That is why we're so disappointed.

"We were talking at half-time to start in a different way. But we start really bad. In 10, 15 minutes in the second half, when we conceded the third goal we gave up. It was tough on them until the end of the game."

"We competed really well against Manchester City, it was a fantastic game. But then we did not compete three days later. Maybe we were not fresh.

"It's not fair to talk about the players we are missing. From the start of the season we have been missing so many players every single week. One team is competing for the Premier League. The other team is competing with all the circumstances we have.

"The team showed a lack of capacity to resist, that is what is the problem.

"Arsenal is a very good team. But I think we allowed them to play. We gave all the possibility to play and create chances [to them]. That is why we're so disappointed. In some parts of the game it was an even game. But we're too inconsistent."

On Cole Palmer's return date: "We don't know, we need to assess tomorrow. We will see the squad that we have. We need to deal with the situation."

Chelsea

Chelsea manager Mauricio Pochettino speaking to TNT Sports: "I think we started the game not so well. We concede the goal and then it was difficult for us to recover from this goal. I think in the first half we compete after 10, 15 minutes. We could not approach the game like we started in the first half and we didn't compete the way we needed to compete and then when they scored the third it was easy for Arsenal to control the game.

"I think you need to be clinical. Like against Manchester City three days ago, we were not clinical and then today the same thing happened. Difficult performance because it is not nice to see your team play like this when you are mean to have full energy. After three days when you play a fantastic game against Manchester City, today we are disappointed with the performance."

Arsenal

More from Arsenal manager Mikel Arteta speaking to TNT Sports: "It is a big London derby and we know what it means for the fans. We will enjoy it and rest and get ready for the next one.

"What I would like is that the players can manage themselves in the dressing room. You have to leave them some space. They know what they are playing for. That's what holds the team together. My role is to demand of them and also in the right moments make them believe they can do it.

"We have a lot of games coming up. Let's enjoy tonight and let's go back to work."

Great to have you back Dave. Thomas Tuchel anyone?

Dave (yes me again): OK, Louis Theroux is great but back to the question. If Poch is the problem, who replaces him? Don't forget, this is not Poch's team. I blame the owners.

Arsenal

Arsenal manager Mikel Arteta speaking to TNT Sports: "Very happy with the win, with the amount of chances and goals we scored. And with the clean sheet as well it shows the consistency.

"We weren't disciplined enough with some stuff we did in the first half and we needed to be more disciplined and we did that in the second half."

On Martin Odegaard: "We agreed that he was a player with huge talent and he could grow with us. We were convinced he could add something special to the team.

"That's always a question: How are you going to handle a different role [as captain]? He has done it so naturally and he is loved by everyone. With the love that he has, it is enough for everyone to wan to follow him."

Mike Arteta's been speaking to the media. We'll hear from him soon. No sign of Mauricio Pochettino yet...

Martin Keown
Former England defender on TNT Sports

When he came here there was a perception that he was very passive as a player, but there was nothing passive about his performance tonight.

You've got to admire Ben White's honesty. I claim every goal I've every scored at five-a-side, mishit or not.

I don't score many, mind.

Arsenal

Arsenal defender Ben White to BBC Match of the Day: "The first goal I was just in the right place at the right time. The second one was a bad touch and it went in."

On Kai Havertz's performance: "Amazing. He deserves it. He's been outstanding since he's come in. You don't realise how good he is until you play with him.

"Amazing performances from all of us. It's important to keep going and play our best. Obviously it's a massive game. I hope they [Liverpool and Manchester City] are all watching. We can only do what we can do."

Anon: Odegaard is the closest thing I've seen to Bergkamp in a long time

Charlie: Does this finally put to bed the question of our mentality? If we don’t win the league it’ll be because of other team’s excellence rather than us bottling it.

Arsenal goalscorer Leandro Trossard speaking to TNT Sports: "I think the early goal helped us and after that we played so well. We had a lot of chances and we turned them into goals. It's a great night.

"They say clean sheets help you win games. We know if we score the goal we can win 1-0. But, obviously, we want to go for more. Today is the perfect night. I think everyone works so well and hard. I am really happy to be here."

On the title race: "We can only do our own job and that's winning games. We are on track now and we will try and win the rest of the games and we will see what happens."

Rio Ferdinand
Former England defender on TNT Sports

They [Chelsea] were second best all over the pitch today. This was men against boys.

They have been good in recent weeks and this season. I think they were way off it.

Anon: What an embarrassing performance from Chelsea. I think Mourinho is available! Even Lampard would be better than Poch.

The first Mourinho mention of the night...
