Awful Man United was lucky against Watford - Shaw

Manchester United was far from convincing as it beat Watford 2-1, and Luke Shaw conceded it was a performance to forget.

Anthony Martial (L) scored Manchester United's second goal and Marcus Rashford scored the first in the 2-1 win against Watford.

Manchester United was fortunate to beat Watford after an "awful" display at Old Trafford on Saturday, according to Luke Shaw.

The Red Devils marked Ole Gunnar Solskjaer's appointment as permanent manager this week with a 2-1 defeat of Javi Gracia's side that moves it above Arsenal into fourth place, albeit having played a game more than the Gunners.

Marcus Rashford and Anthony Martial scored in each half but Watford was mostly the superior side, with 20 shots to United's eight, and it deserved more than Abdoulaye Doucoure's 90th-minute consolation.

Shaw admitted afterwards that United was lucky to escape with the points ahead of a trip to Wolves on Tuesday, where it was knocked out of the FA Cup two weeks ago.

"I think we made it more hard work with the way we played," said Shaw. "First half, there were times we weren't at our best, but second half - I'll speak the truth: we were awful. We were lucky with the result; we weren't good enough.

"We did have a few chances, but we didn't take them, but the most important thing was three points. We need to get ourselves together again and focus on Wolves."

Shaw set up Rashford for the opening goal with a superb throughball, having won back possession near his own penalty area, and he had faith his England team-mate would not miss when through one-on-one against Ben Foster.

"I'm always confident when Rashy is in front of goal," he said. "I know the movement he does; he likes to get in behind. It was a great finish and great composure, but the most important thing is the three points. We were not at our best and we need to improve on Tuesday."

Shaw was nonetheless happy to win for Solskjaer, having expected the caretaker boss to be given the job on a full-time basis due to his impact since returning to the club in December.

"We were fairly confident the boss was going to get the job," he said. "He's been brilliant since he came in. We've had a couple of bad results but we're looking forward to working with him for years to come."
