Diego Maradona in the Arsenal midfield! Santi Cazorla wins it in his own box, pirouettes away from one challenge, nutmegs another man, beats two more and is finally tackled 65 yards further downfield. This is the best I think I've ever seen Cazorla play.

City bring on Edin Dzeko for the tame Jesus Navas.

"The second goal gave Arsenal that extra bit of energy, out of absolutely nowhere. They are playing so well on the break but is a strangely open second half and you're sure there will be chances for City at some point. I don't think City have been on sparkling form this season, but they've still been winning. I tell you what though, they will have to be sparkling between now and the end of the game to get something out of this. A draw is no good to them."

Manchester City's next league fixture is Chelsea away. Lose today, and lose that - and Chelsea are champions?

Ash Williams: City have done an imitation of the usual Arsenal defending. No one challenged Olivier Giroud.

Stavros Makrozachopo: No Yaya Toure, no champions, simple as that!

Julian Croker: Surely even Arsenal can hang on to a two-goal lead this time?

That would have sealed it! Alexis Sanchez unleashes from 25 yards and Joe Hart beats it clear, just away from the lurking Olivier Giroud. City waste no time getting it down the other end and Jesus Navas side-foots one a David Ospina. No power, no conviction.

Jesus Navas is in behind but again he hits the first defender when he had three men waiting for the cutback. Can City find a goal? They have 20 minutes.

Santi Cazorla has been outstanding this afternoon. A brilliant midfield display. City still look a threat but to be honest David Ospina hasn't been tested anywhere near enough. This could be a damaging defeat.

"There's not much to that goal, there was just no marking whatsoever. I thought Santi Cazorla was going to come off - but well done Arsene Wenger! Cazorla takes the free-kick, but the City defence totally lost Olivier Giroud."

Big! A big, big goal for Arsenal, a big goal in the title race! Manchester City's defending is atrocious as Olivier Giroud gets ahead of Fernando to head home a Santi Cazorla free-kick. He was unmarked six yards out and planted it into the corner.

Alex Oxlade-Chamberlain has covered a lot of turf today but he is off now, Tomas Rosicky is on. Keep the ball, keep the ball...

If Arsenal can hang on - Chelsea will be five points clear at the top of the table. That is a very handy lead at this stage of the season.

Here he is, Frank Lampard is on for Fernandinho. He has 28 minutes to save his new side.

"That is either the best defending I have ever seen in my life or just pure luck from Laurent Koscielny - I am going with the latter. Tomas Rosicky has to be coming on soon because Santi Cazorla looks spent. Cazorla's dead on his feet but this game is suited to Rosicky. Another player suited to this game would be Theo Walcott."

Frank Lampard is coming on. Another chapter to his tale?

How has that not gone in? Jesus Navas for once delivers quality with a low ball across the six-yard box, Sergio Aguero is mentally already celebrating the equaliser but Laurent Koscielny gets a toe to the cross and puts it behind. Brilliant defending.

Theo Walcott scored twice in Arsenal's 6-3 defeat at City last season. His pace could be a potent weapon on the break later in the game. Is he coming on?

"That was a real chance for Arsenal (see 55 mins). There were couple of poor decisions with the final ball, though. Certainly Olivier Giroud could have played a better pass earlier for Aaron Ramsey. Arsenal were so well organised in the first half, you wondered whether they could keep it up because it is just not in their DNA. They're not the kind of players who will want to keep on doing that."

The purists, the technicians, the chess lovers may disagree with me but this has been a brilliant 10 minutes of football. End-to-end, littered with mistakes and half-chances, the threat of a goal hanging over both goals. That's what we want, isn't it?

Paul Lambert won't be able to watch.

It's the only mindset to have Mike. Expect the worst - I hear you.

Arsenal look as dangerous as City to be honest and here's a great chance on the break! They have a three-on-three, Alexis Sanchez inside to Olivier Giroud, he waits too long to find Aaron Ramsey on his left and Ramsey scoops the shot over the top. If the pass was a second earlier, Ramsey scores.
