West Ham United continued their unbeaten Premier League start by stunning Brighton with a clinical counter-attacking display as James Ward-Prowse scored his first Hammers goal.
The win means West Ham end the day top of the Premier League on goals scored, although Manchester City and Liverpool could both leap above them with wins on Sunday.
Ward-Prowse opened the scoring when he tapped in from two yards out in the 19th minute after good work from Michail Antonio.
Jarrod Bowen added a second for the visitors in the 58th minute, bringing down Said Benrahma's cross before poking the ball into the corner.
