David de Gea
Had a quiet first-half, with Jarrod Bowen's goalbound shot inconsequential as it was from an offside position but he pulled off a great save from Kurt Zouma in the 83rd minute. 9
Diogo Dalot
Moved infield regularly to supplement midfield and regularly showed adventure but was also the most dependable defender, intervening on key occasions. 8
Harry Maguire
Off the pace in the first-half and his distribution was largely risk-aversive. Settled for defend-at-all-cost clearances as United held on. 6

Lisandro Martinez
Had little grief from Gianluca Scamacca, other than a sore head from his high challenge. Another solid performance. 8
Luke Shaw
Foraged forward regularly but his delivery on the overlap remains reliably unreliable and West Ham targeted his side as they sought an equaliser. 6
Casemiro
Started his eighth successive game and not as influential as in previous weeks in the Premier League and could have come off. 6
Christian Eriksen
Eriksen was always going to be key in a low-scoring fixture in recent years and he worked the breakthrough beautifully to cross for Marcus Rashford. 7
Anthony Elanga
A first start since September 1 at the expense of the injured Antony and Elanga was harmless. Looked like someone without a United goal since February. 4
Bruno Fernandes
Cushioned the ball perfectly for Eriksen to assist Rashford but his regressive week continued and he was often detached from the midfielders and the forwards. 4
Marcus Rashford
Unfortunate an earlier header was straight at Lukasz Fabianski but leapt like Cristiano Ronaldo to put United ahead. 7
Cristiano Ronaldo
Involved in some decent link-up play in the first-half and got into goalscoring positions in the second but was wasteful. 6
Subs
Scott McTominay
Came on to counter West Ham's more adventurous play. Crossed for Fred to hit the post. 6
Fred
Hit the post with a header. 6
Manager
Maguire and Elanga's selections were enforced and United were always going to have to be patient. The choice of McTominay as a first change was cagey. 6
