Arsenal had a chance to eat into Liverpool's lead in the title race, but instead of ratcheting up the pressure, the Gunners crumbled vs. West Ham.

Arsenal suffered through another 10-man, finish-challenged disappoint as Graham Potter's West Ham United picked up a 1-0 win at the Emirates Stadium on Saturday.

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.

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.

Arsenal's miserable afternoon was compounded when Myles Lewis-Skelly's yellow card for a foul on Mohammed Kudus was upgraded to a red, after the video assistant referee ruled that the teenager had denied the Ghanaian a clear goalscoring opportunity.

On paper, it’s a cosy fixture for the Gunners as the visitors are coming off one of their worst performances of the season in a 1-0 home loss to Brentford. Concerningly, new West Ham manager Graham Potter has lost four of his first six games and won just once.
