Erling Haaland was unable to celebrate his Manchester City home debut with a second goal, but Pep Guardiola's team still easily defeated Bournemouth.
It took Haaland 18 minutes to take his first touch, but he utilised it to set up Ilkay Gundogan for City's opening goal.
Since City had been controlling the match from the beginning, additional goals quickly followed. With a brilliant solo goal, the excellent Kevin de Bruyne increased the score to 2-0. He ran to the outside of the box before bending the ball with the outside of his boot into the bottom corner.
And Phil Foden made sure of the points before half-time, running on to a De Bruyne pass and letting fly with a shot that Cherries keeper Mark Travers got his body behind but could not keep out. Bournemouth spent most of their time defending in a compact 5-4-1 formation, and only forced Ederson into action once, through a Ben Pearson snap-shot from the edge of the area.
They never looked remotely capable of staging a comeback in the second half, which had turned into a stroll in the Manchester sunshine for the home side long before Jefferson Lerma's own goal made it 4-0.
