Man United ends Watford’s perfect start with 2-1 win in EPL
It then took David de Gea’s fingertips save from Abdoulaye Doucoure’s header to ensure United claimed a third victory of the campaign.
Fourth-place Watford is still ahead of United, although the gap between the sides has been narrowed to three points.
“I am very happy with the spirit,” United manager Jose Mourinho said. “I feel a bit frustrated because we had everything in the first half.”
But only two goals. Lukaku steered Ashley Young’s cross into the net with his chest in the 35th minute. The lead could have been doubled almost immediately with former United goalkeeper Ben Foster pushing over a strike from Paul Pogba.
But United would not be made to wait much longer as another Pogba shot from the resulting corner was blocked behind.
This time Young’s corner was sent deep into the box, with Marouane Fellaini’s knock-down skillfully controlled on the chest by Smalling, with the defender on the turn then sending the ball past Foster.
“If we played the second half the way we did the last part of the first half we would be in this moment with a completely different result,” Mourinho said. “The beginning of the second half we let the game go down in intensity and stopped being aggressive. We gave them the chance to be reborn, score a goal and give us a difficult match.”
