The Reds fell behind in only the second minute, when Luke Shaw unluckily diverted an Emil Krafth cross into his own net. Although Bruno Fernandes had a goal ruled out by VAR, Harry Maguire soon equalised with a firm header.
Fernandes was denied by Karl Darlow from the penalty spot in the second half but powered Ole Gunnar Solskjaer's men in front with four minutes left. Aaron Wan-Bissaka then provided the third with an explosive finish before Marcus Rashford got in on the act in the dying seconds.
