Manchester United have struggled to see off Watford at Old Trafford but scrambled to a 2-1 win as Ole Gunnar Solskjaer marks his stint as permanent manager.
Returning Anthony Martial would have done better by spotting and giving the ball to Marcus Rashford after Man United broke through in the 18th minute. The Frenchman carried the ball and cut back but it was late as no one in red was around to maximise the chance.
Rashford, in the 28th minute, scored the opening goal for the hosts who had been backpedalling for the better part of the evening. Luke Shaw sprayed the ball on Rashford's path before the England striker clinically received and slotted past Foster.

Two fine chances for United wet unconverted the first one coming in the 33rd minute with Martial was culpable as his 10-yard shot went down and close to Foster to collect. The other chance arrived in the 44th minute with Rashford the culprit this time around. Kabasele did well to block the shot that appeared less ambitious in the first place.
Watford's chance in the 58th minute was the closest they came to restoring parity. Doucoure's shot was blocked by Shaw and Deeney robbed Matic the bouncing ball and teed up Hughes whose curled effort went just off the left post.
Martial doubled United's lead in the 72nd minute after Lingard played him through. Although it was debatable whether the winger was offside, Martial finished even under pressure from Foster. He was later replaced by Marcos Rojo.
