PREM: Arsenal v West Ham preview
West Ham will welcome back Michail Antonio from a hamstring injury for Wednesday's Premier League clash with Arsenal.
Antonio will play some role in the match at the Emirates Stadium, although boss Slaven Bilic refused to indicate whether he is ready to start.
Aaron Cresswell will miss the next two games with a thigh injury but Diafra Sakho could be on the bench for the first time since suffering a back injury in November.
Arsenal will be without Laurent Koscielny after the defender was forced off at half-time in Sunday's 2-2 draw with Manchester City due to an Achilles issue, and the France international is awaiting a scan to determine the severity of the problem.
Goalkeeper Petr Cech (calf) and Lucas Perez (thigh) are also missing while Santi Cazorla (Achilles) will not play again this season, although both Aaron Ramsey and Alex Oxlade-Chamberlain could shake off knocks to be involved.
