Arsenal name the same side as the one beaten 1-0 by Aston Villa last weekend, meaning David Raya is back in for Aaron Ramsdale in goal following the midweek draw with PSV Eindhoven.
Kai Havertz completes the midfield along with Declan Rice and Martin Odegaard.
Gabriel Jesus again leads the line, flanked by Gabriel Martinelli, who has shaken off a knock,and Bukayo Saka, but there’s no place in the squad for Jorginho, who misses out with a foot problem.
