Antoine Semenyo and Evanlison scored as Bournemouth sealed their first-ever win against Manchester City at Vitality Stadium.
The Cherries, in good form after picking up four points from their last two games against Aston Villa and Arsenal, started quickly and full of positivity.
Ederson was forced into a double save after just two minutes as he denied Semenyo and Justin Kluivert.
With the tone set, Bournemouth continued to press high and they were rewarded in the ninth minute when Milos Kerkez’s cut-back from the byeline was turned in by Semenyo.
City failed to muster an attempt on target during a largely frustrating first half.
Bournemouth came out for the second period full of confidence and were close to doubling their lead in the first minute, but Ederson was sharply off his line to keep Evanlison’s effort out.
Evanlison made sure with his next opportunity, though, sliding to meet Kerkez’s low ball and nestling it into the bottom corner.
The hosts should have made it three moments later but Adam Smith, presented with an open goal, blazed over the bar after Marcus Tavernier’s shot came back off the post.
City finally registered an attempt on target in the 80th minute, albeit a tame one, with Erling Haaland struggling to get any power on his volley.
And two minutes later, Josko Gvardiol headed beyond a despairing Mark Travers to offer hope but the Premier League champions were unable to grab an equaliser.
The defeat means City slip to second after Liverpool came-from-behind to beat Brighton, while Bournemouth climb up to eighth.
