Pep Guardiola picked Gabriel Jesus to play against Liverpool because he is fresh from his substitute appearance this week.
Guardiola made three changes to his Manchester City side from the team he named against Atletico Madrid, with Jesus, Phil Foden and Kyle Walker replacing Nathan Ake, Ilkay Gundogan and Mahrez.
Walker's return after his Champions League suspension and Foden's recall following his match-winning cameo were expected, but Jesus's selection was more unexpected, especially in place of the in-form Mahrez. However, Guardiola said he prioritised players who are fitter after the difficult Atletico match on Tuesday.
