The teams: Arsenal v Chelsea
Eden Hazard returns to the starting line-up.
Having been rested for the win over Stoke on Saturday, the Belgian will play in attack with Alvaro Morata.
Arsenal bring in Ainsley Maitland-Niles for injured Saed Kolasinac on the left. Laurent Koscielny has failed to recover from injury in time so Rob Holding comes into their defence. Mesut Ozil has been passed fit. He is preferred to Alex Iwobi.
Chelsea are expected to line-up as follows:
Arsenal: Cech; Chambers, Mustafi, Holding; Bellerin, Xhaka, Wilshere, Maitland-Niles; Ozil, Lacazette, Sanchez.
Subs: Ospina, Mertesacker, Coquelin, Elneny, Walcott, Iwobi, Welbeck.
