Arsenal head coach Unai Emery has a number of selection headaches ahead of Wednesday night's Carabao Cup quarter-final at home to rivals Tottenham.
Full-backs Hector Bellerin (calf) and Sead Kolasinac (thigh) will not be risked, while centre-back duo Rob Holding (knee) and Konstantinos Mavropanos (groin) are still sidelined - although Sokratis Papastathopoulos is back after a ban.
