Duo return for Arsenal

Arsenal will have midfielders Abou Diaby and Francis Coquelin back from hamstring injuries for tomorrow’s Barclays Premier League clash against Chelsea at Emirates Stadium.

Defender Laurent Koscielny returns from a two-game suspension, but on-loan midfielder Yossi Benayoun is ineligible against his parent club.

Mikel Arteta will not recover from the ankle injury sustained against Wigan in time to feature again this season, while England midfielder Jack Wilshere (ankle) has already been ruled out along with German centre-back Per Mertesacker (ankle).

Provisional Squad: Szczesny, Sagna, Vermaelen, Koscielny, Gibbs, Song, Ramsey, Rosicky, Gervinho, Walcott, van Persie, Fabianski Djourou, Santos, Jenkinson, Diaby, Oxlade-Chamberlain, Coquelin, Chamakh.
