Chelsea v Arsenal line-ups: one Blues change, Fabregas decision, Gunners pair passed fit
Chelsea have opted to recall Pedro for the visit of Arsenal.
It is the only change from the side that drew 1-1 with Liverpool on Tuesday, with Willian dropping to the bench.
Blues boss Antonio Conte has resisted the temptation to select Cesc Fabregas against his former club, instead sticking with Nemanja Matic alongside N’Golo Kante.
Arsenal have made three alterations after the midweek home defeat by Watford.
Aaron Ramsey is sidelined for three weeks with a calf injury but Alex Oxlade-Chamberlain has been passed fit to replace him.
Hector Bellerin returns at right-back, with Gabriel – sent off in this fixture last season – dropping to the bench.
Olivier Giroud is fit but he too is only a substitute, with Theo Walcott recalled and Alexis Sanchez pushed further forward.
Chelsea: Courtois; Azpilicueta, Luiz, Cahill; Moses, Kante, Matic, Alonso; Pedro, Costa, Hazard.
Subs: Begovic, Zouma, Terry, Fabregas, Chalobah, Willian, Batshuayi.
Arsenal: Cech; Bellerin, Mustafi, Koscielny, Monreal; Coquelin, Oxlade-Chamberlain; Walcott, Ozil, Iwobi; Sanchez.
Subs: Ospina, Gabriel, Gibbs, Maitland-Niles, Reine-Adelaide, Welbeck, Giroud.
