Arsenal welcome London rivals Chelsea to the Emirates Stadium this evening in another crucial clash in the Premier League title race.
The Gunners can temporarily retain their spot at the top of the table with victory over Frank Lampard's men. They dropped to second place over the weekend after Manchester City defeated Fulham.
Victory over the Blues will see Mikel Arteta's men go two points above their title rivals. On paper, they should do just that, with Chelsea losing their last five games and not managing a win since March. However, in any local derby, form goes out the window.
