And that is all from us today. A big day for Chelsea, without them even playing.

Don't worry, Garth's team of the week is on its way to us. Santi Cazorla must be nailed on for a place...

See you tomorrow for Everton v West Brom. Over and out.

More from Wenger: "I took Francis Coquelin from France at the age of 16 and he is now 24. He has gone through some difficult periods, but he is a learner and I always kept faith in him.

"A few months ago, I told him he had to play, he accepted going down to Charlton and had some convincing performances. He came back and I have played him, and he's done very well.

"We are still looking [for a defender in the transfer market]. There is no progress, but if you have a good idea you can text me."

More from Gunners boss Arsene Wenger: "The difference is that first of all we have injured players back, and also that we know it's a very important period and the confidence of the team is high and some players are in very good form.

"When we scored the first goal it was much easier for us to control them. We looked dangerous when we won the ball. We didn't always take advantage of the situations in the final third.

"What is for sure is that it increases the level of belief and confidence in the team, with five very important months in front of us.

"Since Cazorla plays centrally, he is at a level of his career where he can have more influence. He is fantastic because he gets you out of pressure in tight situations. He shows you how important it is to be two-footed in the middle of the park. He passionately loves the game.

"My initial reaction was 'Penalty'. Somebody told me that we were a bit fortunate to get it. I will have to see it again."

Manchester City manager Manuel Pellegrini at the post-match news conference: "We didn't play a very good game. We ran a lot, we had a lot of possession, but we didn't have creative ideas to try to find the space against a team that defended very well. We conceded two goals from set pieces.

"The game at Stamford Bridge is a very important game. We must close the gap to two points. I hope that we are going to recover and play in the way we have so far, except for this game.

"I think it was not a penalty. In that moment the game changed - we were nervous after the goal - but I don't want to have the excuse of the penalty."

606 phone-in

Over on BBC Radio 5 live, 606 is already in full swing and Ian Wright and Kelly Cates are taking your calls.

Tony, an Arsenal fan, says: "I'm speechless, I don't know what to say. It's redemption for Wenger."

Jason, a Manchester City fan, says: "Arsenal didn't do anything to stop City, it was the referee's decisions."

James, a Hull fan, says: "Big changes need to be made, but I think it might be too late this season."

Lines are open and you can have your say. Call: 0500 909 693, text 85058 or it's @bbc606, external on social media.

BBC radio presenter Danny Baker: "On Antiques Roadshow in 50 years someone will bring this PL Season to the table:

"Its a nice example but this was not a vintage year. £40"

Manchester City manager Manuel Pellegrini, speaking to BBC Sport: "We must be clear that we did not play well. We had a lot of possession but after that we did not have the ideas to be a creative team against Arsenal, who defended very well. We improved in the second half, especially in the first 15 minutes, but another goal in set pieces came in our best moment. [Before then] I do not remember one chance from Arsenal.

"The penalty... I don't know if it was a penalty or not a penalty. But I don't want to misunderstand that I think the result is because of the referee blowing for a penalty that he thinks is a penalty. We had enough time and enough of the ball to draw the game, until they scored another goal from the set piece.

"Yaya Toure is a very important player for us, but we played without Sergio Aguero and now we must play without Yaya. This team cannot depend on just one player. That is not the reason why we lost. It is important to play against Chelsea and close the gap to two points, but even if we don't win and it is five points, there is still 45 points to play for, so we have a lot of time to recover the lead Chelsea have. The most important thing is to improve the way we are playing, because the last five goals we have conceded were from set pieces."

As we wind down our Premier League coverage for the day, don't forget that there is action ongoing in Africa and Spain - where Lionel Messi has just scored a header.

Manchester City manager Manuel Pellegrini on Sky Sports: "There are two principal reasons [why we lost]: one was the penalty, which changed the game. I don't think it was a penalty, but it was unnecessary [for Vincent Kompany] to do it. And we were not creative - we didn't have the ideas to cause damage in their defence. Without creativity it is difficult to score goals.

"The movement of Kompany allows him [Nacho Monreal] to dive. I am not saying it was a bad mistake of the referee. The penalty changed the game, but it was not the reason we lost.

"Of course, I always give credit to the team that wins the game. Arsenal played very concentrated. We ran the whole game, pressed very well, but we didn't have the ideas of how to create the space in their defence.

"We still have to play against Chelsea so it will be a very decisive game. We will try to win that game to close that gap again."

Arsenal manager Arsene Wenger, speaking to BBC Sport: "Santi Cazorla has been superb for a while now but today he was maybe even more influential. The way the whole team defended gave him a lot of the ball, and when you give him the ball you always have a chance to relieve pressure. [In our performance] you felt the great unity, solidarity, togetherness and compactness in our team.

"From outside it looked to be a penalty. I would have to see it again, but from the bench it looked a penalty. We had many opportunities to score the second goal earlier but did not take them, but the pitch was not the best and they defended well.

"Today we scored first and that changed things. At Liverpool we were close to winning the game and today we have done it. It is important to get that out of the way - to show that we can win away in the Premier League, and that will make us stronger. I think we carried that a while, everybody questioning our defensive solidity, and to get that today is very important."

Manchester City boss Manuel Pellegrini does not think his side should have conceded a penalty today, but admits that the challenge from Vincent Kompany was 'unnecessary.'

More reaction to come.

Arsenal manager Arsene Wenger on Sky Sports: "I felt that we were well-disciplined, well-organised, had a good solidarity and overall we kept a good control of the game. We could even have done better on counter attacks.

"We played high up in their half and very deep in our half and it worked. Sometimes, the fact that you have to find solutions internally is a blessing. People are very quick on their judgment, you forget that we had many defenders out all season, as you saw today the centre-backs are a good partnership and it takes time to get back to that level.

"It's down to everybody doing their job. The first goal dictates the way of the game in these big games - today we scored first.

"We looked in control away from home and we finally got a big win in a big game away from home. What is pleasing is that reinforces the belief of the team. To feel that you can do well is very important."

There are plenty of stats coming out of today's game which illustrate how poorly Arsenal have played on the road down the years.

Arsenal today win a Premier League away trip to the defending Champions for the first time since a 1-0 win at Manchester United on 8 May 2002. That was a big win...

Since he arrived in the Premier League at the start of the 2012-13 season, Olivier Giroud has scored 11 headed goals, two more than anyone else.

Arsenal midfielder Mesut Ozil:, external Wow, 2-0 at the Etihad Stadium! Great performance from the whole team!

Arsenal midfielder Aaron Ramsey, speaking to Sky Sports: "We felt like in the past we were too open but today we definitely defended as a team and did not give any room in the middle for David Silva to get into those little pockets he loves.

"We forced them wide and we dealt with it. And obviously we took advantage of our chances going forward."

Arsenal midfielder Santi Cazorla speaking to BBC Sport: "Today the team played very well. When we defend well, we have so many chances to win the game. Olivier Giroud was amazing, he's a very important striker for us."

Edmund Emiowei: Easily Arsenal's best tactical performance of the last five seasons. Well done Arsene Wenger - for once he gets it spot on!

Mike, Liverpool: Blood pressure through the roof and relief unbounded. Can't believe Arsenal have collected three points and kept a clean sheet. Would love to say that l was confident, but that would be a lie!

Ashraf Farid, Doncaster: Santi Cazorla was fantastic, but what about Francis Coquelin? Have Arsenal finally found that elusive defensive midfielder?

Arsenal midfielder Aaron Ramsey on Sky Sports: "Everybody else won on the weekend so it was important for us to get the win, and hopefully we can build on this and have a good second half of the season.

"It's not an easy place to come, and Manchester City have made this a bit of a fortress, but we've done well and got the win. Santi Cazorla was different class."
