Ralf Rangnick has fallen to his first loss as Manchester United manager after Joao Moutinho's 82nd-minute strike earned Wolverhampton a 1-0 win in the English Premier League on Tuesday and a first victory at Old Trafford since 1980.
Outplayed for much of the game, United's players looked like they would survive for a point until Moutinho met a defensive headed-clearance by controlling the ball at the edge of the area and driving in a volley that rolled just inside the post.
This was the toughest test of Rangnick's opening six matches in charge and United at times couldn't get near Wolves, whose passing and movement was sharper in its first game in two weeks following Covid-19 issues in the squad.
Wolves had 19 shots in total, with the 15 in the first half the most by a visiting team at Old Trafford since the league's statistic supplier, Opta, began recording stats in 2003.
There were murmurings of discontent from the home fans, too, with some jeering Rangnick's decision to substitute Mason Greenwood just before the hour.
