More last-ditch defending, this time from the Hammers. More blocks than a game of Tetris in the second half, as Aaron Cresswell gets in front of Martin Odegaard's strike to stop the Gunners drawing level.

How did that stay out?!

Superb defending from Kieran Tierney to first block Jarrod Bowen's shot from close range and then also keep out Michail Antonio's goalbound shot - not sure he knew much about the second.

Great game, this.

Calum Chambers has been brilliant, Arsenal's best attacking player today when no doubt he was brought into the side for his defensive attributes.

The right-back has created both the Gunners' goals.

West Ham are the first team to score two own goals in a Premier League game since Swansea in January 2017 - which was also against Arsenal.

Martin Odegaard's delivery is good, but West Ham scramble clear.

Vladimir Coufal is the first player in the book, for a foul on Pierre-Emerick Aubameyang to the right of the box. Dangerous...

Better from West Ham after soaking up all that Arsenal pressure, the hosts are able to enjoy the ball for a few moments before Michail Antonio tries an optimistic strike from a tight angle and fizzes it well off target.

David Moyes is not happy!

Jesse Lingard is running towards goal but Jon Moss blows his whistle for a foul in the build-up. The West Ham man was away...

Moyes is still grumbling away on the touchline.

Naim Rahman: Get Auba off. There’s no fight from him. He is strolling. Not leading by example. He can’t be bothered.

West Ham look to play out from the back but give it away. Jesse Lingard is forced to haul down Alexandre Lacazette to stop the Gunners breaking.

Martin Odegaard's delivery reaches David Luiz at the back post, but he lofts the ball harmlessly over the crossbar.

Martin Ward: This is Arteta's team now. The old guard are gone, the new are in. They look worryingly mid table. Where is the class. Where's the dominance and flair. Worried

Saka hoists it into the box this time and again West Ham head clear. The hosts can't get hold of the ball, and wave after wave of Arsenal pressure continues to build.

Lacazette then spins on the edge of the box and gets a left-footed effort off, but Fabianski can claim comfortably.

Calum Chambers is the Arsenal danger man at the moment, he's running the show from right back. West Ham are having to dig in and Chambers' deep cross is headed clear.

Arsenal have started the second half really well. They finished the first in lively fashion, too. Every West Ham player is back in their own half at the moment.

I think if Lacazette had gone down that would have been a penalty, because he was pulled back.

It was a lovely ball over the top and Lacazette is pulled back by Coufal. He stayed on his feet and tried to dink it over the goalkeeper.

So close to a second for Arsenal!

Alexandre Lacazette latches on to Calum Chambers' flicked pass, coaxes the ball over Lukasz Fabianski and it looks to be dropping into the net, but Issa Diop is there to acrobatically hook it off the line.

Here we go.

The Gunners get the second half under way.

Big 45 coming up then, surely Arsenal can't start as slowly as they did in the first...

An unwanted stat for Tomas Soucek, though he's keeping great company - the midfielder is the first player to score both a goal and an own goal in the same home Premier League game for West Ham since Frank Lampard against Leicester at Upton Park in November 1998.
