West Brom will feel hard done by after they became the first team to lose at Old Trafford in the Premier League for over four months.
Bruno Fernandes scored his seventh goal of the season with a retaken penalty as Manchester United claimed a controversial first Premier League home win since July with a 1-0 defeat of West Brom.
United have endured their worse home start in the top flight for 48 years, but finally secured three points at a ground that used to be such a fortress at the fifth attempt.
They needed some fortune to end a six-match run without a home victory that stretched back to last season, though, as referee David Coote overturned his decision to award struggling Albion a penalty at the start of the second half.
Fernandes breathed a sigh of relief after he was adjudged to have brought down Conor Gallagher and the midfielder was a lucky man soon after when he was given a second chance to score from the spot.
Sam Johnstone tipped away Fernandes’s first attempt after Darnell Furlong was harshly penalised for handball, but came off his line too soon, and the United talisman did not pass up another opportunity to open the scoring.
