Just a day after securing his £65 million ($87 million) move from Bournemouth, Semenyo was among the scorers as City put League One Exeter to the sword at the Etihad.

Erling Haaland started but was remarkably not among the goals before being withdrawn at half-time.

Rico Lewis scored twice, while Max Alleyne, Rodri, Tijjani Reijnders, Nico O'Riley and Ryan McAidoo were also on target for City and Exeter netted two own goals.
