Arsenal’s Premier League title challenge has been dented by an unexpected 1-0 home loss to West Ham that featured a fifth red card of the season for Mikel Arteta’s team.

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.

Arsenal face West Ham looking to turn up the pressure on title rivals Liverpool. After Liverpool were held to a draw at Aston Villa on Wednesday, Arsenal can cut their lead at the top of the Premier League to five points before the leaders travel to Manchester City on Sunday.
