United looking to put this game to bed. This time defender Phil Jones makes a run forward but his shot is blocked and pops up into the hands of Heurelho Gomes.

Can Watford hold out and nick a goal themselves?

United peppering the opposition with attempts at goal now. This time it's Bastian Schweinsteiger with a drive that sails over the bar. The second goal is coming for the visitors...

"A great opportunity for Manchester United to double their lead is lost, but they are straight back into the ascendancy after the break."

Etienne Capoue's loose pass is picked off by Memphis Depay. The Dutchman lays a pass into the path of Jesse Lingard, whose goalbound shot is saved well by Heurelho Gomes. A top save from the Watford man, but it should have been 2-0.

United get us back under way. How will Watford respond in the second half?

Watford make a change at half-time as central midfielder Nathan Ake comes on for Spaniard Jurado.

"At times Watford have looked almost in awe of Manchester United, who have been in total command right from the word go. 

"Memphis Depay scored a splendid goal to give them a deserved lead, but the home side can do much better and I'm sure their manager will have reminded them of that in the dressing room."

Striker Marcus Rashford, 18, and midfielder Sean Goss, 20, are on the bench for United today. But who are they?

The United website describes the teenager Rashford as a striker with a "powerful shot".

Rashford has been with United for several years and helped the side retain youth trophy, the Milk Cup, in 2014.

Goss was signed from Exeter City for an undisclosed fee in the summer of 2012.

The United website says his playing style is similar to that of Michael Carrick's. United fans will be hoping the player enjoys a similar stellar career at Old Trafford.

Will either get a runout in the second half?

Femi John Ayotebi: Sunday morning football played at lunchtime on Saturday! Boring!

The Public Observer: Man Utd play the same way ALL the time (boring) but are praised when they win and criticised only when they lose.

David Broome: United lucky they are playing a poor Watford - very sloppy in midfield again with Mata and Schneiderlin particularly bad.

Louis van Gaal will be happy with that half from his boys. Seeing plenty of the ball and a goal to show for it.

"Watford are just not asserting themselves, they need to get some rhythm, a few series of passes, but Manchester United are in control. 

"It's not been a vintage performance from the visitors but Bastian Schweinsteiger and Morgan Schneiderlin look more than assured in midfield, as do the two centre-backs behind them." 

Memphis Depay's 11th-minute strike the difference at the break.

Ben Watson's corner is poor and easily dealt with. Manchester United can clear the ball without trouble.

Watford earn their first corner in the last minute of the half...

Heurelho Gomes nearly gifts the visitors a goal! His loose kick is pounced upon by goalscorer Memphis Depay, but his ball forward finds Juan Mata in an offside position. They should have made more of that chance.

Quick passing from the visitors sees them in a promising position in the final third, but Ashley Young turns back inside and the momentum is lost. 

Not long to go until half-time, can Watford grab an equaliser before the break? Louis van Gaal's men haven't conceded for six and a half hours of play now. How do you breach that watertight backline?

Cameron Laws: Well this change of formation has killed off our early dominance.

Phillip Baker: I remember that David Platt goal so well (see 27 mins). I had just announced that i thought he was rubbish, when....

Memphis Depay turning it on now, showing why United forked out so much money for him in the summer.

He skips with the ball from the left, before unleashing a low drive that Heurelho Gomes has to get down to to push away. No howler from the Watford goalkeeper this time, he dealt with that one well.

"The ball seemed to hold up a little in the wind, sitting nicely for Etienne Capoue to strike it but the Frenchman's effort was wild.

"Watford still haven't tested David de Gea at all so far." 

Allan Nyom working hard deep inside the Untied half and wins the ball back, before whipping in a dangerous delivery that Phil Jones has to head away. 

The ball falls to Etienne Capoue on the edge of the box, but the Frenchman blasts the ball over the bar. It was a chance and he should have done better with no opposition man around him.
