Gibbs out of Besiktas clash

Arsenal will be without defender Kieran Gibbs (hamstring) for Tuesday night’s Champions League play-off first leg against Besiktas in Istanbul.

Centre-back Laurent Koscielny has shrugged off an Achilles problem and midfielder Mathieu Flamini returns after missing the Barclays Premier League win over Crystal Palace, but forward Yaya Sanogo (hamstring) did not travel.

German World Cup winners Mesut Ozil, Per Mertesacker and Lukas Podolski are all not yet to be involved, while goalkeeper David Ospina (thigh), Theo Walcott and Serge Gnabry (both knee) continue their rehabilitation.

Provisional Squad: Szczesny, Monreal, Chambers, Koscielny, Debuchy, Cazorla, Sanchez, Ramsey, Wilshere, Arteta, Giroud, Martinez, Oxlade-Chamberlain, Rosicky, Campbell, Coquelin, Flamini, Bellerin.
