Alexis Sanchez is expected to shake off a thigh injury in time for Arsenal’s showdown with Chelsea in the FA Cup final on Saturday.
Sanchez limped off against Everton last weekend but is likely to be passed fit while Alex Oxlade-Chamberlain is also in contention after recovering from a hamstring strain.
Laurent Koscielny, however, is suspended and Gabriel will miss out with a knee injury, meaning Per Mertesacker could make his first start in almost 13 months.
Late decisions will also be made on Kieran Gibbs, who has a thigh problem, and Shkodran Mustafi, who is struggling with illness.
Provisional squad: Cech, Ospina, Martinez, Oxlade-Chamberlain, Bellerin, Holding, Mustafi, Koscielny, Mertesacker, Monreal, Gibbs, Maitland-Niles, Coquelin, Xhaka, Ramsey, Ozil, Walcott, Iwobi, Sanchez, Perez, Welbeck, Giroud.
