Arsenal must plan without key stars against Sunderland
Arsenal will be without Alexis Sanchez and Santi Cazorla for Saturday's Barclays Premier League visit of Sunderland.
The pair were both injured in last weekend's draw at Norwich with a hamstring injury sidelining Sanchez and Cazorla facing up to four months out with a knee problem.
Laurent Koscielny was also forced off with a hip complaint but is in contention to return against the Black Cats, as is Theo Walcott who has overcome a calf problem. Jack Wilshere (leg), Mikel Arteta and Kieran Gibbs (both calf), Francis Coquelin, Danny Welbeck and Tomas Rosicky (all knee) are all expected to miss out.
Provisional squad: Cech, Ospina, Monreal, Debuchy, Chambers, Koscielny, Gabriel, Mertesacker, Ramsey, Flamini, Ozil, Oxlade-Chamberlain, Reine-Adelaide, Iwobi, Campbell, Walcott, Giroud.
