Erik Lamela is being assessed over a thigh problem ahead of the north London derby.
The attacking midfielder sustained the injury during Wednesday’s Champions League victory over Inter.
Meanwhile, right-back Kieran Trippier is undergoing the final stages of rehab and conditioning as he works his way back from a groin problem.
Central midfielder Victor Wanyama continues to receive treatment for an injury to his right knee, while fellow midfielder Mousa Dembele (ankle) and centre-back Davinson Sanchez (hamstring) are both continuing their rehabilitation.
Kick-off at the Emirates Stadium on Sunday is at 2.05pm.
