Southampton also boosted their chances of staying up by beating Wolverhampton 3-1. Brighton, though, are still in trouble after losing 5-0 at home to Bournemouth to drop to 17th.
Paul Pogba's calm nerves and David De Gea's quick reflexes kept Manchester United in the hunt for a top-four finish. Pogba scored two penalties to give United a 2-1 victory over West Ham at Old Trafford, the second coming shortly after De Gea had denied West Ham a potential winner by palming away a header from Michail Antonio with a superb one-handed save.
The win was much-needed for United but the performance wasn't convincing as the hosts were outplayed for large spells and benefited from two disputed refereeing calls. West Ham had a goal disallowed for offside before the hosts were given a soft penalty as Robert Snodgrass was judged to have fouled Juan Mata when the two collided in the area.
"We got away with it, to put it that way," United manager Ole Gunnar Solskjaer said. "They deserved to get their goals. But then, it's allowed to have a good goalkeeper, isn't it?"
The win ended a run of four losses in five games in all competitions for United and kept Solskjaer's team two points behind fourth-placed Chelsea.
Tottenham remained three points ahead of United in third by beating already relegated Huddersfield 4-0, with Lucas Moura scoring a hat-trick.
Moura made sure Tottenham did not miss injured striker Harry Kane as the Brazilian winger became the first player to score a hat-trick in the club's new stadium after Victor Wanyama opened the scoring in the 24th minute.
