Manchester City manager Manuel Pellegrini: "Very happy because we won the game. We played very well and had a lot of chances to score the third goal and we defended well. It was a difficult start because they scored with their only chance in the first half.

"We are absolutely confident the way we play and sure we are going to win the game. If we scored the third goal we could play well and not so tight.

"We had the chances but didn't score. The best way to score goals is to play as a team. The second goal was beautiful play.

"We have to play seven games more before the end of December and we have to fight for all of them."

Arsenal legend Thierry Henry has urged Gunners fans to "appreciate" Arsene Wenger and football writer Amy Lawrence agrees that some supporters can easily forget the Frenchman's impact.

"Whenever Arsene Wenger retires, people will look at his career as a complete works and they will assess everything he has done over that time," she says.

"Right now people are looking at this season and you can't expect critics, or football fans, to constantly look at this bigger picture. Unfortunately we take it too far the other way, where when you win and you're a genius then the next week have a nightmare and you're an absolute loser.

"Perspective is a great. But expecting people to have perspective, to look at 18 years' work, is difficult when you've just chucked away a three-goal lead at Anderlecht or a one-goal lead at Swansea."

"With so much of the pre-match focus on Danny Welbeck, it is easy to forget that Manchester United striker Robin van Persie also facing his former club, after spending eight prolific years in north London between 2004 and 2012.

"The 'rule of the ex' seems to apply to the 31-year-old Dutchman, who has bagged three goals in four matches against the Gunners since moving to Old Trafford in 2012.

"Van Persie has topped the Premier League scoring charts with both clubs but his current form is under scrutiny and he admitted last week that his three goals in nine league games this season are "not enough".

"That is especially true when you consider the chances he has missed. Of the 35 players to have scored three or more goals in the Premier League this season, Van Persie has the worst shot conversion of them all - 13.6%, according to Opta.

Leicester boss Nigel Pearson: "I thought we played pretty well under the circumstance - a difficult run of results - and created some good chances. You could argue we did enough to win the game.

"Before today we had only kept one clean sheet so there always positives from getting a point. It is frustrating for the players because they played well and created many opportunities.

"We tried to win the game. I felt we were more likely to win than our opponents. We were aggressive with the way we went about things but it didn't quite happen for us."

Chelsea manager Jose Mourinho: "It was comfortable but I thought in the first half we played amazingly well. In the first half we have to be 3-0, 4-0, 5-0 up. But the quality of our football was there. I don't remember seeing many times football of that dimension. We made the pitch very wide, we created spaces in the central area, and the result should be better than 2-0. We are playing well. We are getting the results that we deserve and I'm pleased that we did. Especially after 15 days when I have no players to work with. But it's three important points."

On Diego Costa after two weeks' rest: "It's easy to see the difference in him now, because now he can run, he can sprint, he can challenge for every duel."

"It was a really big win.

"We have had two weeks to clear our heads and I think the performance was good other than the first 20 minutes.

"It should have been more comfortable but we'll take the win after the last month or so. We looked good in possession."

"Arsenal have given away a cardboard cut-out of Danny Welbeck with today's programme and the former Manchester United striker will be on the pitch for real after shaking off a hamstring injury to start against - and face for the first time - the club he supports and spent 15 of his 23 years playing for after joining them at the age of eight."

From Johnny, London: So bogey teams do exist! So many things went wrong for West Ham today. 5 key players out, a dive from an opposition player, an offside goal and getting no points even though we were the superior team!

Vince in London: I'm an Arsenal fan. However all of you writing United off are overlooking one thing. Wenger and Arsenal are and have been mentally and tactically inept against united since 2009. Put United shirts on a pub team and we still wouldn't beat them.

"If Arsenal striker Danny Welbeck needs any extra motivation before facing his former club then he only had to flick through this morning's newspapers - where headlines like "None of us rated Wel" and "You're just a sub" tell the story of how Louis van Gaal has no regrets in letting him leave Manchester United in September.

"Welbeck's bit-part status at Old Trafford is underlined by how little he has featured in meetings between these two sides in the recent past - playing in just two of a possible 15 games since he made his United debut in 2008.

"But his record in this fixture when he has played is remarkably good - he scored the winner at Emirates Stadium in January 2012 and scored the first goal in United's 8-2 demolition earlier that season. More goals today might just make Van Gaal eat his words."

Swansea manager Garry Monk: "We are a little disappointed but they are a very good side and they had their chances. We had a couple of chances at the end we should have taken. I am just very happy with the journey we are on. We are competing in every game.

"We got a good goal and the players' mentality changed a little bit as we tried to protect it. A learning process for us, the players are fully committed. We pushed an exceptional team very, very close.

"Of course City will push for the title, I don't doubt that."

"The statues outside Emirates Stadium are a reminder of happier times for Arsenal, but also demonstrate how it has been a long time since United's status was also so low.

"It is more than 16 years since they last faced each other with both teams outside the top four, when Tony Adams - now immortalised in bronze outside the Gunners' ground - scored Arsenal's first goal in a 3-0 win in September 1998.

"That was the season United went on to win the treble and Arsenal finished second, a point behind them. Those days must seem like a million miles away for both clubs now."

Arsenal striker Danny Welbeck should have an element of revenge on his mind when he faces Manchester United for the first time, says ex-England midfielder Jermaine Jenas.

"You don't want to get carried away and lose sense of game plans but it is important to keep being sold at the forefront of your mind," says Jenas.

"He was at one of the biggest clubs in the world, had Robin van Persie who wasn't playing that well being picked ahead of him and you've got a young lad, an international who came through the ranks, and all of a sudden he's being told that he is no longer needed.

"If I was Danny Welbeck that would be at the forefront of my mind and I'd be ready to go."

Will in Oxford: That Arsenal back line looks vulnerable, Arteta will have his work cut out. Luckily for them though the Utd back line looks even worse! Should be a good watch for the neutrals, what price on 3-3?

Lee, Manchester: For all the slagging off of Man United this season, how many teams above them have had to play a different back four in every game and include at least one newly promoted reserve, let alone two at the emirates??!!

"In the first half we played amazingly well," is Jose Mourinho's summary of his side's display.

Full reaction to come.

"Arsenal's attack is boosted by the presence of Alexis Sanchez, despite concerns over his freshness after his international duty for Chile, and by the early return of Olivier Giroud, back a month ahead of schedule after breaking his leg at the end of August. The Frenchman is on the bench."
