Well actually Aymeric Laporte isn't ready. The referee gives him about 45 seconds to come on and he's still getting his shinpads on so eventually play just restarts with City having 10 men.

John Stones can't continue, although he can walk off the pitch. Aymeric Laporte replaces him.

City defender John Stones is down injured, hurting his hamstring while stretching for the ball.

The physios are on.

Two minutes added on.

This is the best 0-0 you are going to see and an absolute tactically elite game of football.

Riyad Mahrez is just unable to keep a crossfield ball in play.

Decent ball from Grealish but Haaland went too early.

A great FA Cup tie, though. It is end to end.

Rob Holding has already been struggling with Erling Haaland. A yellow card makes this very risky. I'd be tempted to replace him at half-time if I was Mikel Arteta. William Saliba and Ben White are on the bench.

First yellow card of the game. Arsenal defender Rob Holding pulls Erling Haaland to the ground as the Norwegian tries to run onto a return pass.

Haaland smelt a bit of blood there with that mistake from Tierney.

It wouldn't quite sit for him and went wide off his foot.

Dangerous from City.

Erling Haaland gets a good City move going with a bursting run. It ends with Jack Grealish failing to find the big man with a cross.

A freak Kieran Tierney ricochet launches the ball towards his own goal. Erling Haaland barges past Gabriel but shoots wide. The Gunners defender just put him off enough I think.

You know what is interesting. Arsenal left it 2 v 2 at the back when Ortega had the ball.

If that was Ederson, I think he would have got that ball down to Haaland who had a great run then. Ortega hasn't got that ping yet though.

Leandro Trossard is already looking like a great signing for Arsenal, to give them more options if Gabriel Martinelli is injured or tired.

It was good play again from Leandro Trossard, who is causing young Rico Lewis all kinds of problems. Nketiah just got across Akanji but it went the wrong side of the post.

Lovely run from Jack Grealish to get away from Takehiro Tomiyasu but his through ball to Erling Haaland is cut out.

Trossard has been fantastic tonight. Showing his pace and a great ball with his left foot.

Three or four yards out but another warning sign for City

Good pressing from Arsenal, not giving City any time on the ball.

We are seeing players like Rodri making mistakes. That is not like him.

Leandro Trossard burns Rico Lewis this time on the left and crosses for Eddie Nketiah, who stabs a shot just wide at the near post.

It is 0-0, half an hour in but you have to admit, Arsenal have been the better team.
