Arsenal have Emile Smith Rowe back among the substitutes for tonight’s Europa League clash with Olympiacos.
The attacking midfielder has been out of action since February 28 with a hip issue, but took part in full training on Wednesday before Arsenal fly to Athens.
After drawing to Burnley on Saturday, Mikel Arteta has made several changes for this Europa League last-16 tie - with Gabriel Magalhaes coming in at centre-back for Pablo Mari.
Arteta has also brought Hector Bellerin back in at right-back after the Spaniard was rested at the weekend.
Arsenal starting XI (4-2-3-1): Leno; Bellerín, Gabriel, Luiz, Tierney; Partey, Xhaka; Saka, Odegaard, Willian; Aubameyang.
