Arsene Wenger today announced that neither Alex Oxlade-Chamberlain or Jack Wilshere will be involved against the Hammers tomorrow.
The Arsenal manager said: “It’s very difficult to say when he (Oxlade-Chamberlain) will be back. We have to respect his recovery.”
Jack Wilshere is also set for an extended spell on the sidelines. The midfielder was expected to recover quickly from minor ankle surgery a few weeks ago but is yet to return to full fitness.
Provisional Squad: Ospina, Monreal, Koscielny, Mertesacker, Bellerin, Coquelin, Cazorla, Ozil, Sanchez, Welbeck, Giroud, Szczesny, Walcott, Chambers, Gibbs, Akpom, Flamini, Rosicky.
