The midfielder misses out on the squad completely, as the Gunners make just one change from the draw with Chelsea. Takehiro Tomiyasu comes in at left-back, with Oleksandr Zinchenko dropping to the bench.
After the arrival of his first child, Aaron Ramsdale missed Saturday's 2-2 draw with London rivals Chelsea in the top-flight, but he is back in the squad here. David Raya was shaky at Stamford Bridge, but keeps his place in Spain.
Kai Havertz was another player pushing to start, along with the likes of Leandro Trossard and Fabio Vieira, but Mikel Arteta has proved reluctant to make changes.
Arsenal are in need of a win tonight after losing their last Champions League fixture away in Lens. The Gunners are currently sat second in Group B.
