The Hammers’ goals came courtesy of Andriy Yarmolenko’s superb first-half strike and Aaron Cresswell’s outstanding free-kick in the second period, which ensured the hosts took all three points at the London Stadium.
It was a quiet opening to the encounter with the weather appearing to dampen both sides resolve, quite literally.
It took 15 minutes for the first shot of note, which came courtesy of Nemanja Matic, whose effort from around 25 yards was well held by Lukasz Fabianski.
Soon after, David De Gea held Yarmolenko’s speculative effort, before Marcus Rashford’s dangerous run was snuffed out by the Hammers’ defence.
