Arsenal squad vs Sunderland revealed ahead of crunch Premier League clash at the Emirates
The Gunners must beat the relegated Black Cats to keep their hopes of a top-four finish alive
Arsenal could be without Alexis Sanchez for Tuesday's Premier League visit of relegated Sunderland.
The Chile forward took a kick to the thigh in Saturday's win at Stoke and faces a test before the clash with the Black Cats.
Laurent Koscielny is set to miss out after a recurrence of an ongoing calf problem while Alex Oxlade-Chamberlain (hamstring) faces a race to be fit for the FA Cup final.
Koscielny should be fit for the final league game of the campaign, a home match against Everton, as well as the FA Cup final against Chelsea on May 27.
But he is also having to work consistently on his ankle to keep himself fit and available for selection.
"I have some problems," he said when asked about his Achilles.
"Now it is better. I know it is a difficult injury because you need to work every day on this. Every morning I have my treatment for my Achilles and I know I need to do this to the end of my career.
"Now, every day I do this and it is okay but sometimes with all the games we play every three days, it is difficult and I need to have a rest to recover well for my Achilles.
Provisional squad: Cech, Ospina, Martinez, Bellerin, Holding, Gabriel, Mustafi, Koscielny, Mertesacker, Monreal, Gibbs, Maitland-Niles, Coquelin, Xhaka, Ramsey, Ozil, Walcott, Iwobi, Sanchez, Perez, Welbeck, Giroud.
