Manchester City have made five changes from the side who beat Brighton at the weekend – most of them come in defence.
Ederson returns in goal, while Ruben Dias, Rico Lewis and Nathan Ake come into the backline instead of Kyle Walker, Josko Gvardiol and John Stones.
The only change in the midfield and the attack sees Jack Grealish start over Phil Foden, as Jeremy Doku keeps his place.
