And we leave you with a message from former Leicester striker Gary Lineker...

Don't forget, you can follow Aston V Liverpool here, where Daniel Sturridge and James Milner have given the reds a 2-0 lead.  

Cheerio.

Some stats for you to get your head round...

- Leicester City still haven’t won a league game against Arsenal since November 1994 

- Theo Walcott’s 70th minute goal was Arsenal’s first shot on target in this match, while Danny Welbeck scored their sixth and final shot on target in this game.

- Danny Welbeck's goal was Arsenal's 100th goal scored in 90+ mins of a Premier League game; more than any other side.

Arsenal manager Arsene Wenger talking to BBC Sport: "The effort, energy, intensity was all good. Leicester defended very well but we had bad luck to be 1-0 down at half-time. We were relentless after that - we should have scored more goals.

"Mesut Ozil was fouled in the build up to Leicester's goal and the penalty looked very harsh. I'll have to look again but it didn't look like one."

"It was a pivotal moment today because the mathematics meant it could be eight points or it could be two points. That is a great change.

"There's a long way to go, we play a lot of big teams. But we had a bad spell where we couldn't win for four games and have now won two on the bounce. We have come out of that bad spell and still have a good chance."

Guy from Nottingham: So pleased that Arsenal won. Hard work throughout the match paid off. Hodgson talked about English attacking talent, all goals scored by English players.

Dan Vitran from Leicester: So that's how it feels to have your heart broken on Valentine's. What ever doesn't kill you makes you stronger. Foxes never quit. But that wasn't even a free kick ball was out of play ...

Leicester manager Claudio Ranieri talking to Sky Sports: "It was a fantastic match, very fast. I don't know if in a normal match that our two yellows cards was a sending off. They were normal fouls, but not yellow cards. I think the referee was too severe to us for the sending-off. 11 v 11, I'm sure we win the match. The match was full of fouls so why send off a player? Come on. 

"We know Arsenal are a fantastic team, they move the ball quickly and have skill, but we had to concentrate. We tried to counter attack and we controlled the match very well.

"They scored with the last chance - they were smarter than us.

"We are still top of the table, got two points more - we must carry on and smile. We lost to our opponents - we must say well done."

Arsenal keeper Petr Cech talking to BBC Sport: "We had to concentrate in the final stages because any counter attack was becoming more and more dangerous as we searched for the winner. It was tricky.

"What I like about our win is that it is always tricky when opponents are down to 10 men. They have good organisation and are fighting for their lives. We managed to break them down and create chances. We kept missing chances but kept composure and kept coming.

"We had so many half chances where we could have scored more."

"if you have a cushion of five or eight points it is a big difference. We overturned eight points to two - it is significant difference."

On Danny Welbeck: "It has been a great day for him because working hard to come back. we could see last couple of weeks that he was ready and sharp and confident in training. He really deserved."

Arsene Wenger tells Sky Sports the Arsenal team chanted Danny Welbeck's name when he came back into the dressing room after scoring the winner.

A nice welcome back after nine months out.

The Arsenal boss also admits it was a very close decision whether to include Welbeck in the squad or not.

And another Danny Welbeck-inspired meme on Twitter...

Some meme's dropping in on social media...

I think Aaron enjoyed that...

Vince: Think I pulled my hamstring celebrating that goal in my living room

John McGuigan: A tale of two Danny's

Haji Shakeel: Thank you Man U and Van Gaal for giving us Welbeck. Everyone was laughing at Arsenal for signing him.

In the minute after Arsenal's winner, there were 18,000 tweets including the word Welbeck...

England manager Roy Hodgson spoke about the options he has in attack last night.

Looks like Danny Welbeck has just rejoined the mix.

Arsenal's match winner Danny Welbeck on Sky Sports: Dying seconds, we kept pushing, had chance after chance. I missed the first opportunity and tried to make amends. It is important and the most important thing is to get the win. It has been a roller-coaster for me, a difficult moment and my family and friends know what I have been through.

Arsenal substitute Theo Walcott: "This man hasn't played for nine months and to get into the mix like that, special players come into into big games. That could be massive."

Richard, St. Albans: Devastating for Leicester but if you look at their run in I still fancy them if they don't let this knock them.

Tom, Sheffield: I think it's safe to say that Arsenal are now everyone's least favourite premier league team -  

James Marshall: would you believe it Danny Welbeck, what a comeback  

A look at the heat maps below (Arsenal left, Leicester right), shows how much the Gunners were pushing...

Leicester's Jeffrey Schlupp sums up the feeling of anyone connected to the Foxes...

Alistair Bruce-Ball
BBC Radio 5 live commentator at the Emirates Stadium

"That could be a huge moment in the title race because you thought Leicester were going to hold on there. The Arsenal players are still out there doing a lap of honour.

"Who is going to win it? I have no idea."

Howard Horner: HUUUUUUUUGE! That makes Arsenal favourites for the title to me. DANNY BOY!!

James Hammond: As soon as Welbeck came on that was coming. In a season full of incredible moments, no way was that not happening.

Ali Mason: The. Best. Season. Ever.
