What a wonderful comparison Pat. Santi Cazorla was top class, more nutmegs today than a spice rack.

"Santi Cazorla, I'm going to make an analogy about him that probably only people over 80 will understand - Emil Zatopek. (Czechoslovak long-distance runner best known for winning three gold medals at the 1952 Summer Olympics in Helsinki)

"He always looked like he was going to fall over and die, that is the way Santi Cazorla looked for the majority of the second half - exhausted. Yet he kept on going, he got the assist for the second goal, and his power and strength as the game went on was fabulous. That boy will sleep well tonight. He's so tired he's being carried off the park on the shoulders of Alex Oxlade-Chamberlain."

"Manchester City have today not looked like a team that can overhaul Chelsea. The man that Manchester City are desperately missing is Yaya Toure and while he is away at the African Cup of Nations will City's title defence falter?

"Arsenal have waited a long time for this and it was an outstanding performance. Particularly from Santi Cazorla with one of the best displays by a midfielder we've seen by a visiting team here."

It's looking pretty for Chelsea then. A five-point lead with 16 games to go, and City to travel to Stamford Bridge in two weeks' time.

Arsenal move on to the shoulders of Manchester United too. Can Southampton stick with the top four?

"Arsenal had such a positive attitude - the way they have played speaks volumes about the manager. People were having a real dig at Arsene Wenger before today, and you do understand that as they have been a distance away, but today he got it absolutely right. Every single Arsenal player worked their socks off and it has won them the game. Francis Coquelin, he was shouting as loud as anybody and getting everybody going, his attitude has been superb.

"Sergio Aguero, we talked about him so much before the start of the game but he had an absolutely minimal impact. David Silva, of whom you expect so much, didn't create a single chance the whole game."

Arsenal pull off a memorable win. Chelsea are the big winners.

I have to be honest here, I may have said when the teams came out that I had some doubts over an Arsenal back four containing Nacho Monreal and Hector Bellerin. They have both been excellent.

Chance! Arsenal could have a third as Mathieu Flamini bursts into the box, Olivier Giroud is square for a tap-in but he hesitates and the chance is gone.

FOUR MINUTES added on.

That could have set-up a grandstand finish - but Vincent Kompany heads wide from close range. Not his day.

"City seem to have lost their belief. If they push it they might be able to draw level here, there is still injury time to be played. But they seem to have run out of ideas just now."

Santi Cazorla has delivered 'one of the best individual midfield performances away from home in the Premier League' according to our man in the booth Jonathan Pearce.

Three minutes left, Edin Dzeko clumps a shot wide.

Arsenal defend a corner in style, breaking and turning it into an attack. Sergio Aguero's method of tracking Kieran Gibbs is one I used to deploy - he hangs onto his shirt and yanks him back. Booked.

Aguero looks done. City look done.

Tony, Wivenhoe, Essex: Heart in mouth time. Come on you Gooners! Three points beckon.

Garrett, County Down: Alexis Sanchez rubbing off on Santi Cazorla. What a run! (see 75 mins)

Fergus, Manchester: While Cazorla has been brilliant, why is no one mentioning Francis Coquelin? I've lost count of the number of interceptions he's made!

Ten attempts, only three on target. That's the story of Manchester City's disappointing afternoon in front of goal. Double sub for the Gunners, off come Alexis Sanchez and the injured Aaron Ramsey, on come Kieran Gibbs and Mathieu Flamini.

Santi Cazorla has had a brilliant game - and I've just seen his celebration for the second goal. Top, top class. One for the dancefloors of the world.

"This is the best I've seen Arsenal play in yonks. Disciplined, canny, energetic, explosive and combative."

Brilliant one-touch stuff inside the penalty area sees David Silva and Frank Lampard tee-up Stevan Jovetic, but his low shot is deflected wide. That needed to go in.

Chris White: Is this City side only capable of winning the title every two years, when the African Cup of Nations doesn't happen?

#Vote4Jim: The way Santi Cazorla is playing, Mesut Ozil can be saved for unimportant cup games. Yes, I said it.

Oker: Cazorla man-of-the-match.

As well as three points, Chelsea have put a seven-goal swing between themselves and Manchester City this weekend. The clubs were level on everything just a few weeks ago so that could end up being decisive. You never know.

Just over 10 minutes to go...
