Arsenal v Hammers team news

Arsenal are without Santi Cazorla, for the match on Wednesday night and goalkeeper Petr Cech (calf) is still not fit, so David Ospina is expected to deputise in goal.

Lucas Perez (thigh) will miss this game, and Laurent Koscielny (achilles) is expected to sit the match out having been taken off at half-time against City.

Alex Oxlade-Chamberlain (hamstring) and Aaron Ramsey (calf), however, are both in line to make their comebacks.

The Irons have Michail Antonio set to make his return, although Aaron Cresswell will face a late fitness test and Arthur Masuaku stands by to replace him.
