Arsenal will be without midfielder Tomas Rosicky for Tuesday’s Barclays Premier League clash with Southampton.
The experienced Czech Republic international only returned from a knee problem ahead of Saturday’s FA Cup victory over Burnley but suffered a thigh problem during the game and will again spend a spell on the sidelines.
Alexis Sanchez is pushing for his first start since a hamstring issue in November while Mohamed Elneny is still waiting for his Premier League debut having made his bow in the cup win. Francis Coquelin, Danny Welbeck and Santi Cazorla (all knee) and Jack Wilshere (leg) are out.
Provisional squad: Cech, Ospina, Monreal, Gibbs, Koscielny, Gabriel, Mertesacker, Bellerin, Debuchy, Chambers, Ramsey, Elneny, Flamini, Ozil, Oxlade-Chamberlain, Reine-Adelaide, Iwobi, Sanchez, Campbell, Walcott, Giroud.
