Bukayo Saka misses Arsenal’s Europa League clash with Olympiacos tonight.
The teenager was forced off at half-time of Sunday’s win over Tottenham and was being assessed ahead of Thursday’s last-16 second leg at the Emirates - but Saka has been left out of the squad.
Pierre-Emerick Aubameyang was dropped to the bench on Sunday for disciplinary reasons, but returns to the starting lineup here.
There are further changes to the side, with Mohamed Elneny coming in for fellow midfielder Thomas Partey and Hector Bellerin starting at right-back - but Gabriel Martinelli is among the subs.
Arsenal lineup: Leno, Bellerin, Luiz, Gabriel, Tierney, Elneny, Xhaka, Ceballos, Smith Rowe, Aubameyang, Pepe
Subs: Ryan, Okonkwo, Cedric, Chambers, Holding, Mari, Partey, Odegaard, Nelson, Martinelli, Nketiah, Lacazette
