Arsenal - West Ham United live updates

FULL TIME: Arsenal 3 West Ham United 0

Monreal looks to have been chopped down in the box by Byram but the result is no penalty. Very lucky! Should have been off too.

Into the first of three added minutes here.

Fernandes with a swerving shot on target but Martinez was behind that. Not West Ham’s day.

There won’t be much stoppage time here. The result will mean west Ham are just four points above the drop zone.

Olivier Giroud scores his fifth PL goal as a substitute this season, an outright league high. He was previously level with Nolito (4).

Arsenal have turned their advantage in possession into goals tonight. They don’t do that often enough.

That's Giroud's fifth goal as a sub this season. Game definitely over!

GOAL ARSENAL! The Ox feeds Giroud and he bends a superb shot inside the far corner.

Oxlade-Chamberlain and Ramsey on for Walcott and Elneny.

West Ham sub: Noble replaced by Fernandes.

Xhaka’s shot comes off the chest of Randolph but Giroud can’t react swiftly enough to plant home the rebound.

Sam Byram shown the yellow card for a poor challenge on Sanchez.

Lanzini stings the hands of Martinez and that’s their first meaningful shot on target.

Ozil plays in Walcott but he runs slightly wide and his cross is out for a goal kick.

Arsenal looking very comfortable in possession now and this is bad news for West Ham. Don’t look like getting back into it.

Theo Walcott reaches double figures in league goals for the second time, after he netted 14 PL goals for Arsenal in 2012/13.
