Arsenal meet Everton for the second time in four weeks, looking for revenge after the Toffees toppled them at Goodison Park with a 1-0 win that threatened to derail the Gunners' title charge.
It looks as if Mikel Arteta has managed to get things back on track for the league-leaders, but he is now well-versed in the kind of threat this Everton side possess under new boss Sean Dyche. This game has been marked on the calendar for a while from an Arsenal perspective, as it is their game in hand on title rivals Manchester City.
Should the Gunners win on Wednesday night, it will take Arsenal five points clear at the top of the Premier League. Anything less and it will be viewed as a huge opportunity missed with Pep Guardiola's side chomping at their heels.
