Wojciech Szczesny is suspended after his red card against Galatasaray on MatchDay Two, while Colombia international David Ospina (thigh) is not match fit, so 17-year-old Ryan Huddart will be on the bench.

England international Calum Chambers returns to the defence after missing Saturday's 2-2 Barclays Premier League draw against Hull through a one-match ban. Forward Lukas Podolski is available again following illness, but Theo Walcott is still not fully match fit after his recovery from nine-months out with a knee injury.

Laurent Koscielny (Achilles), Mesut Ozil (knee), Yaya Sanogo (hamstring) and France forward Olivier Giroud (fractured foot) are all out, along with long-term absentee Mathieu Debuchy (ankle).

Provisional Squad: Martinez, Gibbs, Chambers, Mertesacker, Bellerin, Arteta, Wilshere, Ramsey, Cazorla, Sanchez, Welbeck, Huddart, Podolski, Rosicky, Campbell, Oxlade-Chamberlain, Monreal, Flamini.
