Arsenal will be without England midfielder Jack Wilshere for Wednesday night's Champions League clash with Borussia Dortmund.

Wilshere is struggling with an ankle injury and stayed behind in London when the rest of the squad travelled to Germany. He will be assessed again on Thursday to determine whether he will be fit to return against Manchester United on Sunday.

Mathieu Flamini (groin), Theo Walcott (abdominal surgery), Yaya Sanogo (back), Lukas Podolski (hamstring), Alex Oxlade-Chamberlain and Abou Diaby (both knee) remain out, but Kieran Gibbs and Serge Gnabry should return after recent knocks.

Provisional squad: Szczesny, Mertesacker, Sagna, Gibbs, Vermaelen, Koscielny, Jenkinson, Cazorla, Ozil, Ramsey, Rosicky, Monreal, Arteta, Giroud, Akpom, Bendtner, Fabianski, Hayden, Gnabry.
