Arsenal can trim the gap to Premier League leaders Liverpool down to just four points on Saturday as they welcome West Ham to the Emirates Stadium. Racked by injuries up front, Mikel Arteta's side had to dig deep last time out, before two late goals from auxiliary striker Mikel Merino secured them victory at Leicester.

So Mikel Merino starts after his super-sub appearance off the bench against Leicester. He replaces Raheem Sterling in attack, joining Ethan Nwaneri and Leandro Trossard. The other change sees Riccardo Calafiori replace Myles Lewis-Skelly at left back.
