The England winger came off in the second half of Wednesday's Champions League win over Sevilla with an ankle problem, but he trained on Friday and holds his place on the right-hand side.
Mikel Arteta has only made one change to the side from that European success, as Oleksandr Zinchenko returns to the backline over Ben White, who is a notable absentee from the matchday squad alongside Martin Odegaard.
As a result, Takehiro Tomiyasu - who played at left-back in midweek - will shift over to the left-hand side, and Leandro Trossard has kept his place in attack despite Eddie Nketiah's return from an ankle issue.
Meanwhile, Burnley boss Vincent Kompany has named an unchanged starting lineup from last weekend's 2-0 loss to Crystal Palace, as Josh Cullen accepts a place on the bench following a suspension.
Michael Obafemi and Aaron Ramsey have both made the matchday squad after recovering from injuries, while Jay Rodriguez and Zeki Amdouni link arms in a two-pronged attack.
