Scott McTominay scored the only goal of the game as Manchester United booked their spot in the FA Cup fourth round with a slender 1-0 win over Watford on Saturday. 

McTominay was one of only two survivors from the EFL Cup semi-final defeat to Manchester City on Wednesday and the midfielder – captaining the Red Devils for the first time – headed his side in front after just five minutes.  

Eric Bailly and Juan Mata squandered good chances to extend United's lead before the interval, while Dean Henderson had to be alert to thwart Adam Masina.  

United rarely threatened a second during a dismal second half but they saw things out with the minimum of fuss to inflict a 10th straight defeat for the Hornets at Old Trafford.  

The hosts wasted little time stamping their authority on the tie, McTominay heading home his fourth goal of the season from Alex Telles' outswinging corner in the fifth minute.  

United goalkeeper Henderson was out quickly to deny Masina soon after, while Bailly flashed a header wide from another dangerous Telles ball into the penalty area.  

Mata fired straight at Daniel Bachmann following a superb flicked pass from Donny van de Beek as United ultimately failed to add to their advantage before half-time.  

Solskjaer brought on Marcus Rashford and Anthony Martial with just over 20 minutes remaining in a desperate bid to inject some life into the home team’s stuttering attack.  

Rashford should have put the seal on the win, but his low effort after a fine run was too close to Bachmann.

Daniel James knows the pressure is on to seize any first-team opportunities he gets at Manchester United ahead of the FA Cup tie with Watford.

United host their Championship opponents in the third round on Saturday and James believes the competition retains a special place in the football calendar.

The Wales winger, who scored a famous FA Cup goal while he was at Swansea City against Brentford, is hoping to be involved at Old Trafford.

James impressed against Leeds United last month and was also in the team against Leicester City, but they were two of only five Premier League starts he has been handed this season.

Having featured in 33 Premier League games last season, he knows the competition for places at United is tougher this time around, with the club sitting level on points alongside champions Liverpool at the top of the table.

"I have been working hard in training every day and the manager knows I am ready when called upon," James said to United's website.

"I will just keep working hard in training and doing what I do.

"Being at this club, there is always going to be lots of competition and the forwards have been doing so well. 

"So it is about when I do get my opportunity, I have got to take mine. That is the way I have been looking at it. 

"I have not been playing as much so I have been able to do a lot more stuff in training, extra stuff, and I have to keep doing that and look at things I can improve and also work on the things I am good at.

"It [the FA Cup] means everything. Growing up, there have been some unbelievable games over the years.

"I was at Swansea when I watched Jesse Lingard's extra-time goal [for United in the final against Crystal Palace]. It is a special competition."

Asked about his memorable goal, the winger added: "It is a great memory and a special moment.

"There are not many times when the whole pitch is open. I just had to keep that composure and when it went in the back of the net, I knew it was a special goal."
