Find out who is missing through injury and who is in a race against time to prove their fitness in the Premier League this weekend.

Arsenal miss the chance to close the gap on Premier League leaders Liverpool as West Ham end a four-match winless run with a stunning victory at Emirates Stadium.

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.
