Twenty minutes to go. What do Arsenal have in the tank? Three of their first 11 have come on since half-time so this is a stronger team than the one which started the game.

Gabriel Martinelli is caught offside.

Straight after the goal Arsenal brought on Oleksandr Zinchenko and Gabriel Martinelli for Kieran Tierney and Leandro Trossard, who was quieter after a good first half.

That was beautiful. The way Ake turned that in. What a finish.

Matt Turner is going to wish he had a couple more inches on his fingers there.

That was a striker's finsh. He uses the defender and curls it around him into the corner, Jack Grealish has done so well and Julian Alvarez has made a real difference.

It's a very unlikely goalscorer in Ake. He took it well - swept it into the corner of the net. Lovely finish.

Eddie Nketiah is inches away from levelling but Aymeric Laporte cuts out a cross just before Nketiah tucks in at the back post.

It is starting to settle down again after a ferocious start to the second half from City.

Arsenal are looking to just knock it around at the moment.

Just five shots each, a combined three on target. It's not been the classic we might have hoped.

Ilkay Gundogan miscontrols the ball out of play.

Craig Smith: Second half just showing how important Thomas Partey is to this squad. We look a lot more fragile defensively.

Nicholas Walker: Are Man City players allowed to pass to anyone else but Haaland in the final 3rd? It seems he has a monopoly.

Mahrez hasn't been as effective tonight as he has been in previous games and Walker will slot straight in for Lewis. Like for like subs.

Arsenal's first chance of the second half. Out of nowhere the ball drops to Fabio Vieira on the edge of the box but he slices his volley wide.

Mahrez had a great ball to De Bruyne.

Great save from the keeper.

Then Erling Haaland runs straight into the shoulder Matt Turner just hurt as they go for a Riyad Mahrez cross, but the keeper is OK.

Matt Turner is straight back in the action and does really well. He gets down low to punch away a Kevin de Bruyne ball across the six-yard box.

Luckily for Arsenal they have number one keeper Aaron Ramsdale on the bench.

But actually Matt Turner is playing on.

City are looking slicker now.

De Bruyne is getting into the right positions.

Promising for City, as they've got Arsenal on the back foot now.

Arsenal keeper Matt Turner is down holding his shoulder. The referee stops play so he can get treatment.

It appears he hurt it whole doing a one-handed punch from a Kevin de Bruyne cross.
