Youngster, Jesse Lingard scored his first Manchester United goal as Louis van Gaal’s side beat West Brom on Saturday.
Winger Lingard, 22, curled home from the edge of the box early in the second half to give the hosts the lead.
Substitute Saido Berahino missed a superb opportunity to equalise late on when he headed over from close range.
Juan Mata then made the win safe from the penalty spot late on after Anthony Martial was fouled by Gareth McAuley, who was sent off.
The victory keeps Manchester United fourth in the Premier League, while West Brom are 12th.
It was also a first win in three league games for the hosts, who have not conceded in 550 minutes.
There were nervy moments during the match which necessitated the Manchester United fans to chant ‘attack, attack, attack’ in response to the perceived defensive structure employed by Van Gaal.
