Bruno Fernandes scored his first Manchester United goal before Anthony Martial added an exquisite second in a 3-0 win over Watford on Sunday.
The result lifted United two places up to fifth on 41 points from 27 games, three behind fourth-placed Chelsea and one ahead of Tottenham Hotspur. Struggling Watford stayed 19th on 24 points.
The home side looked disjointed in the opening 20 minutes but Fernandes converted a 42nd-minute penalty to register his first United goal before Watford had an effort ruled out for handball following a VAR check early in the second half.
United doubled their lead in the 58th minute when Martial picked up his own rebound after Ben Foster blocked his initial attempt, left Etienne Capoue dumbfounded with dazzling footwork and dinked the ball over the keeper.
Greenwood put the icing on the cake with another individual goal of the highest quality in the 75th minute, unleashing a piledriver into the top corner after he found space on the edge of the penalty area.
