Arsenal make the journey across London on Sunday to face West Ham in a battle with big implications at both ends of the Premier League table.
Mikel Arteta's side are aiming to restore their six-point lead on Manchester City in the title race, with the champions hammering Leicester 3-1 on Saturday, while West Ham are still scrapping just to stay in the league. David Moyes and co drew 1-1 with Belgian side Gent on Thursday but return their focus to domestic matters with the chance to go six points clear of the relegation zone.
Despite the scrutiny on Moyes, the Hammers have only lost one of their last seven games in all competitions and this season could end in the club's first European trophy in nearly 60 years. As for Arsenal, it feels as if only the title would leave fans feeling satisfied after a campaign above expectations, with City breathing down their necks.
