Man City 2-0 Bournemouth

BBC Sport at Etihad Stadium
Not only have Manchester City not been beaten this season, they have not even been behind.
The latest they have had to wait for an opening goal is 27 minutes, at Stoke on 20 August.
Bournemouth had got just over halfway towards that time at Etihad Stadium, only for De Bruyne's 15th-minute free-kick to break their resistance. The Belgian opened the scoring at exactly the same point of last Saturday's Manchester derby.
A tall task had become even more difficult after Kelechi Iheanacho's finish.
