Arsenal’s main injury concerns lie in defence ahead of the north London derby with Spurs.
Hector Bellerin has been ruled out after missing the Gunners’ midweek Champions league tie with a small groin problem. Mathieu Debuchy is expected to deputise at right-back as he did in Munich. Laurent Koscielny is also a concern after failing to appear off the bench in midweek due to a minor hip problem. Should Koscielny be passed fit, Gabriel will again be expected to battle it out with Per Mertesacker for the centre-back spot alongside the Frenchman.
Wenger handed a start to Joel Campbell on the right-flank in the win over Swansea last weekend, and with the injuries in the squad limiting Wenger’s options, Campbell, who got himself on the scoresheet in Wales, looks set to retain his place.
Alternatively, the Gunners boss could be forced to shift either Mesut Ozil or Santi Cazorla to the flanks, with Mathieu Flamini recalled in central midfield.
Up front, Walcott’s absence will give Olivier Giroud the opportunity to maintain his current goalscoring form.
Danny Welbeck, Alex Oxlade-Chamberlain, Tomas Rosicky, Aaron Ramsey and Jack Wilshere remain on the sidelines through injury. Mikel Arteta and David Ospina could make the squad, having returned to training following injury.
Having said this, here is how Wenger is expected to lineup his side against Spurs.
