Chelsea v Arsenal preview
Arsenal are sweating on the fitness of Alex Oxlade-Chamberlain and Olivier Giroud ahead of Saturday's trip to Premier League leaders Chelsea.
With midfielder Aaron Ramsey (calf) definitely out, manager Arsene Wenger will hope Oxlade-Chamberlain can overcome a slight knee problem to take the Welshman's place alongside Francis Coquelin.
Giroud also took a knock in Tuesday's defeat to Watford but is expected to be fit, while Danny Welbeck should return to the squad after being rested. Santi Cazorla (Achilles) and Granit Xhaka (suspended) are both out.
Chelsea head coach Antonio Conte must decide whether to recall winger Pedro, who lost his place to Willian for Tuesday's draw at Liverpool.
Conte also has the option of selecting ex-Arsenal midfielder Cesc Fabregas if he opts for a more attacking line-up.
