Five home wins on the bounce for the Gunners. They are into the top four.

West Ham were woeful on a costly night.

Seconds to go. Arsenal still looking for a third Bukayo Saka has space near the box but chips his pass for Emile Smith Rowe behind the scorer of the second goal.

Granit Xhaka looks to stick a cherry on top but fires a shot from range way over the bar.

DJMANNIE: West ham never a threat before down to 10 men, Arsenal deserves tonight victory.

Matty: Emile Smith Rowe! His finishing has improved so much. Such an intelligent shot to pull it into the near post, particularly on his weaker foot. Fantastic performance today which makes the overreaction in response to the Everton game even more clear.

Arsenal are managing this well. Keeping the ball at the right end of the pitch as far as they're concerned. Passing West Ham out of it.

It doesn't. Straight into the wall from Said Benrahma.

There will be five added minutes. Surely it's not enough time for West Ham to get anything from this?

Tomas Soucek is fouled clumsily on the edge of the box. West Ham have a dangerous free-kick.

This has to go in if the Hammers have any chance of snatching something...

Hats off to Arsenal, they have been superb this evening. Last time I watched them was against Everton. Chalk and cheese.

For a second it looks like Michail Antonio might be in after plucking a long ball forward out of the sky. An Arsenal defender manages to just get a boot in to tackle.

A Premier League debut for 20-year-old Harrison Ashby. A right-back. He replaces Pablo Fornals and allows Michail Antonio - who has been filling in at wing-back - to push further forward.

That's easy for Aaron Ramsdale.

Jarrod Bowen clips in a cross but the Arsenal keeper is out to claim. Six minutes to go.

Tattz: Hard not to like this West Ham side under Moyes. He’s got them in such a good place that even with a man down, they are absolutely giving it everything.

Goalscorer Gabriel Martinelli leaves the game after injuring what appears to be his thigh. On comes Eddie Nketiah.

Into the final 10 minutes. Arsenal heading into the top four as this stands.

That was almost game over, though.

Bukayo Saka's first-time shot at the near post from Gabriel Martinelli's low ball is deflected wide off Issa Diop.

This game isn't done yet, despite the chips stacked in Arsenal's favour.

West Ham send on Said Benrahma for Manuel Lanzini.

Southampton

Southampton captain James Ward-Prowse: "I don't think we started the game very well but got back into it, a scrappy goal we conceded ultimately cost us all three points."

On his goal: "I had a good feeling, I have been practicing those during the week and it was against Jack Butland who I played with in the Under-21s, so I thought he might know my technique."
