The only thing Manchester United fans enjoyed more than Ashley Young's stunning free-kick against Watford last night was manager Jose Mourinho's bizarre reaction to it.

Young, who had already given United a 19th-minute lead with a strike from outside the box, stepped up to dispatch a dipping 25-yard free kick into the top corner.

Mourinho was seen on TV looking bewildered after the ball nestled in the back of Heurelho Gomes' net - and fans seemed to enjoy his expression.

Now, the Portuguese has explained just why he looked so befuddled, reports the Manchester Evening News .

He said he was merely surprised Young took the set-piece ahead of Paul Pogba.

"I was surprised that Paul gave him permission," he said.

"I was not surprised with his [Young's] shot, is quite good and his percentage of success in training is quite high, so we knew he could score but Paul is also very good and his shot is normally more powerful, so in that position I was expecting Paul to take it."

United led 3-0 at half-time and the scoreline stayed the same until Troy Deeney's 77th-minute penalty.

Abdoulaye Doucoure slotted in a second to threaten a remarkable Watford comeback before Jesse Lingard spectacularly secured a 4-2 victory for United.

"We had chances for four, five and six we had that in the first-half," Mourinho added.

"We finish the half with that chance for the open goal, we had it in the second half again and again and we didn't score.

"So I think the players had the feeling the game was easy, the game was over, that Watford had no conditions to react. But then they react, they score the penalty, the penalty gave them belief, these mid-table teams have quality and no pressure, they don't feel the pressure that teams with other objectives have.

"So they come with everything, they have no problems to concede four, five or six so they gave us a couple of minutes of real pressure where anything could happen.

"This is football. Last week, Dortmund-Schalke, 4-0, 4-4, and a couple of weeks ago, Liverpool [at Sevilla] 3-0, 3-3. That's football but I prefer to forget the five minutes where we concede the goals and lost concentration.

"I prefer to focus on the good things we did, and we did so many good things, so much in control and really dangerous in attacking situations, to play away from home and score four goals but possible to score seven or eight."
