Extended highlights: Southampton 0-1 West Ham United
Sebastien Haller scored the only goal of the game as West Ham United secured all three points at Southampton on Saturday evening.
Haller fired home after Pablo Fornals knocked Robert Snodgrass' cross into his path to cap a dominant first half display in which the Hammers thought they should have had a penalty for a foul on Michail Antonio. Both referee Martin Atkinson and VAR Jonathan Moss disagreed.
Moss again intervened after the break to rule out an Antonio strike for handball, and Danny Ings hit the bar for Southampton, but West Ham kept hold of their clean sheet to claim the points.
