Joshua King's strike ended AFC Bournemouth's six-hour wait for a goal as they defeated Manchester United 1-0 at Vitality Stadium.
United twice went close to opening the scoring in a bright start. Andreas Pereira fired over while Daniel James's long-range effort went narrowly wide.
AFC Bournemouth took the lead on the stroke of half-time, Adam Smith crossing for King, against his former side, who flicked over Aaron Wan-Bissaka and volleyed beyond David De Gea.
The home side had opportunities to double their advantage after the break, and Callum Wilson forced De Gea into a fine save on 75 minutes.
A first victory in five matches moves AFC Bournemouth up to seventh on 16 points, above Man Utd in 10th with 13 points.
