Ozil and Sanchez could return to bolster Arsenal against Chelsea

Arsenal could welcome back both Alexis Sanchez and Mesut Ozil for their Barclays Premier League clash against Chelsea on Sunday.

Sanchez has been missing since November with a hamstring issue and Ozil sat out last weekend's draw at Stoke due to a foot injury - but the pair are expected to start against the Blues.

Mohamed Elneny is still awaiting his Arsenal debut with fellow midfielder Francis Coquelin back in training following a knee injury but will not feature, nor will Danny Welbeck, Santi Cazorla (both knee) or Jack Wilshere (leg).

Provisional squad: Cech, Ospina, Macey, Monreal, Gibbs, Koscielny, Gabriel, Mertesacker, Bellerin, Debuchy, Chambers, Ramsey, Elneny, Rosicky, Flamini, Ozil, Oxlade-Chamberlain, Reine-Adelaide, Iwobi, Sanchez, Campbell, Walcott, Giroud.
