Save!

Aaron Ramsdale gets down well to stick out a hand and deflect an Erling Haaland shot away from goal. The Norwegian had set himself up for the effort by bullying his way through two Arsenal defenders.

Cesar Azpilicueta now has the joint most own goals for Chelsea in the Premier League, level with John Terry (four).

Brentford haven't had a shot on target yet.

Bukayo Saka finally gets some space in front of him and the ball at his feet down the left.

Forward he goes only to have the ball nicked off his toes by the backtracking Jack Grealish.

That will make a big difference for the home crowd. Supporters are fully energised now. The Forest players will want half time to go quickly so they can get out and try and build.

It's turned into a really good game, this. Fabinho's shot is straight at Lukasz Fabianski.

Kevin de Bruyne again!

He's running the Arsenal defence ragged. He charges away oince more to collect a neat pass. This time he has two men for company, one of whom is Ben White, who makes a crucial block to stop the Belgian's shot.

Pretty sure that intervention prevented it being 2-0.

Now it's West Ham who should be level. Brilliant defending by Virgil van Dijk.

Said Benrahma plays a delicious ball across the six-yard box and Van Dijk sticks a leg out to deny Michail Antonio a chance into an empty net.

From the following corner Antonio heads just wide.

Much better from Arsenal. They have the ball and keep it in City territory, shifting it right and left in search of an opening.

City hold firm, though, and Rodri steps in to claim the ball and then win a free-kick.

Frank Lampard doesn't look happy. This could be P5 L5 for his second spell as Chelsea boss.

Mega chance for Liverpool but Diogo Jota heads wide from close in.

Arsenal have an effort. It's not a great one, with Gabriel rising to head a free-kick well wide, but it is something on which they can try to build.

City are taking control of this game. They are going quick and then slow to tease Arsenal out, trying to force them to press before playing through them.

Oleksandr Zinchenko nearly gets his side in bother with a weak header. It allows Bernardo Silva to nip in but his low shot through some bodies is easily saved by Aaron Ramsdale.

Kevin de Bruyne is taken down by Rob Holding on halfway and immediately gets in the ref's face to say it's not the first time. It's a foul but no more, according to the official.

Virgil van Dijk heads wide from a corner then looks to the referee for a corner which isn't coming. He thinks Tomas Soucek got the last touch.

Forest's goal has gone down as an OG by Brighton defender Pascal Gross, by the way.

That's virtually the last action of a fabulous and frantic first half in Nottingham.

The half-time balti pie will taste sweeter now for the home fans. That's presuming they can even eat because of the nerves.

Arsenal can't get a kick. Chasing shadows.
