The Gunners are fighting to keep their title credentials alive while the Blues could move three points clear of Mikel Arteta’s team and cement their place in the top four. Enzo Maresca has managed to extract more than those that have gone before him but neither coach is alone on sweating on the fitness of some players.

Cole Palmer and Declan Rice are the big fitness concerns for Sunday's meeting. Palmer suffered a knee injury against Manchester United last weekend, while Rice is recovering from a broken toe, which saw him not travel to Italy in midweek for Arsenal's Champions League defeat to Inter Milan.
