Alexandre Lacazette goes down in the centre circle holding his leg. He gets up and hobbles away but will play on. Not sure what happened there.

Shocking, shocking half of football. Mistake after mistake. Gabriel looking like every other Arsenal CB signing over the last 10 years. Awful.

It was a really good response from West Ham. I think they were in the game and Arsenal were sloppy on the ball. The goal came from nowhere, it was a brilliant counter-attack.
It's probably about right. I've not been impressed by Arsenal.

Farai Diza: Michail Antonio continuing from where he left off last season. Too bad the glamour is being taken off by this drab of a match. What a bore. I'm off to the garage to watch paint dry on the wall.

West Ham's Ryan Fredericks is booked for chopping down Bukayo Saka earlier in that move. The ref let play go on but has come back to punish him.

Pierre-Emerick Aubameyang's cross finds Hector Bellerin, who picks out fellow Spaniard Dani Ceballos but he doesn't shoot and the chance is gone.
Arsenal have about four waves of attacks and then eventually it's over.
Arsenal 1-0 West Ham
Arsenal are looking quite comfortable at the moment. They're quite easy on the eye under Mikel Arteta to be fair.
Arsenal 1-0 West Ham
There was a VAR check for a possible penalty against Gabriel a minute ago. It wasn't given, I think because it hit that T-shirt sleeve area that is the new rule. It's hard to keep track these days.
