Phil Foden scored and got an assist as Manchester City claimed a comfortable first Champions League win of the season at Slovan Bratislava.
The England midfielder has struggled to find the form that saw him named PFA Player of the Season last year, but he made the most of only his second start this term.
After Ilkay Gundogan had scored his first goal on his return to City with a deflected strike in the eighth minute, Foden opened his account for the campaign with a composed finish into the bottom corner seven minutes later.
City then hit the woodwork three times as they continued to dominate their hosts, before Erling Haaland grabbed his 11th of the season just before the hour mark, taking the ball past goalkeeper Dominik Takac to slot home.
Foden then cleverly flicked the ball through for substitute James McAtee to get his first City goal in the 74th minute.
Only heroics from Slovan stopper Takac denied City further goals, but the victory was their first in the revamped Champions League format after drawing at home to Inter Milan in their opening fixture.
