Petr Cech could return for Arsenal following a five-game absence when the Gunners host Watford on Saturday.
The keeper has been missing with a calf injury but the 33-year-old could be involved against the Hornets, with David Ospina set to drop to the bench.
If Cech does miss out this weekend he will be available for the trip to West Ham on April 9.
The Gunners remain without injury victims Aaron Ramsey (thigh), Santi Cazorla (Achilles) and Alex Oxlade-Chamberlain (knee), while boss Arsene Wenger has confirmed Jack Wilshere and Tomas Rosicky are back in full training following respective leg and thigh injuries but Watford’s visit will come too soon for the duo.
Provisional squad: Ospina, Cech, Macey, Monreal, Gibbs, Gabriel, Chambers, Mertesacker, Koscielny, Bellerin, Elneny, Ozil, Reine-Adelaide, Iwobi, Sanchez, Campbell, Walcott, Welbeck, Giroud.
