Jarrod Bowen scored on his West Ham United home debut as the Irons defeated the Saints 3-1 at London Stadium on Saturday afternoon.
A performance full of attacking intent throughout saw Bowen take less than a quarter-of-an-hour to put the Hammers ahead with a calm finish from Pablo Fornals' pass.
The Saints struck back inside the first half through Michael Obafemi's placed shot, but a show of strength from Sebastien Haller restored West Ham's lead shortly before the half-time whistle.
Strike partner Michail Antonio added a degree of comfort with a direct goal early on in the second half, a just reward for a game which saw many of West Ham's creative talents rise to the fore.
