Manchester United survived an Aston Villa onslaught - including two goals being disallowed - as Scott McTominay's early strike proved enough to send Ralf Rangnick's team into the FA Cup fourth round
United, who were without the injured Cristiano Ronaldo, took the lead just eight minutes into the game as Fred sent in an inch-perfect cross from the right and McTominay glanced a header past Emiliano Martinez from close range
Villa were celebrating what they thought was an equaliser just five minutes into the second half when Ezri Konsa headed a free-kick back across the face of goal for Danny Ings to bundle home from close range
But after a lengthy VAR review, including Michael Oliver checking the monitor, it was disallowed after Jacob Ramsey was adjudged to have blocked Edinson Cavani
When asked for his thoughts on the decision, Villa boss Steven Gerrard said: "How long have you got? The officials took three and a half minutes to settle that one
 They have looked at two or three things in it
"When VAR is there and they make a decision you have to accept it
 There is nothing you can do to change it
 The easy way out is to blame luck and the officials, we won't do that
"The frustration continued for Villa as Ings again saw celebrations cut short when he raced through and clipped the ball over De Gea for Watkins to tap home, only to see the offside flag go up for the summer signing's initial run
It was the story of the game for Gerrard's side, who despite the early setback, responded well to going behind to McTominay's early header
They did everything but score as John McGinn's long-range effort was kept out by David de Gea before Ollie Watkins rattled the crossbar after turning Victor Lindelof inside as the hosts got in at the break with their lead intact
After the disallowed goals, Villa continued to push for a late equaliser, but it did not prove to be their night as United survived an almighty scare to reach the fourth round, where they will play Middlesbrough
United boss Ralf Rangnick has spoken about the need for his side to take control of games, but there were still plenty of worrying signs as Villa dominated possession at Old Trafford
However, United's interim boss insists he saw progress from the defeat against Wolves last week
"I think we showed a reaction after the Wolves game, that is what everyone expected from us," Rangnick said
 "We knew it would be very difficult against Villa
 In the first half, I thought we did well
 It could have been 3-2 or 4-3 to us at half-time
"In the second half, we were on the counter-attack and we could have made more of those situations
 We took the wrong decisions at times but when we changed to a diamond in midfield, we had more control
"In the last 20 minutes, we had more control
 We fought well as a team together when it was important
 In the end, it was a good win
 That was our goal, to proceed to the next round
"When asked if he saw progress, Rangnick added:"Yes
 To say that this was a perfect game, nobody would believe that of course, it was not
 We still have quite a few things we can get better at but a clean sheet was important today and we worked together
 Still a lot of things to improve but it is easier to do that with a 1-0 win
""It was job done for Manchester United, but only just!"Steven Gerrard will be left scratching his head on the bus home from Old Trafford, wondering how his side didn't get something from this entertaining FA Cup tie
"Villa were by far the better side as they passed their way through Manchester United time and time again, just as Wolves did in their win at Old Trafford in the Premier League a week ago as Ralf Rangnick's side's failings of the last few weeks appeared again
"McTominay and Fred may have combined for what proved to be United's winning goal in the opening stages, but time after time United were overrun in the middle of the park as Villa piled the pressure on the hosts
"The frustrations of the home fans were evident as passes went astray and Villa continued to dominate the game, and on a different day, Gerrard's men would have got their reward
"However, it was to be United's day as they held on for a much-needed win to ease the pressure slightly on Rangnick
"Villa boss Gerrard has called on his side to be more ruthless in both penalty areas after they squandered an excellent opportunity to reach the FA Cup fourth round for the first time since 2016
Gerrard said: "Very tough
 We are out of the FA Cup and coming into this job I saw this competition as an opportunity to have a good run in it
"The lads gave a lot in terms of performance but we need to learn and close the gap from a performance that was nearly good enough
 We dominated for large parts but we were not ruthless enough
"I've seen enough tonight in terms of the performance to know that I can get to where I want to get to but we need to learn and learn quickly
 We need to be more ruthless moving forward, defending crosses we need to be tighter
 We cannot be having people with free headers in our six-yard box
 It is quite clear what we need to iron out and we will do it in the short term
"Despite the defeat at Old Trafford, it's been a big week for Villa with The former Liverpool forward has completed his medical and is currently in France completing paperwork for his work permit
He is set to join up with his new team-mates on Wednesday to take part in his first training session and will be ready to play in Saturday's Premier League match against United
Gerrard will be hoping his former Liverpool team-mate can make the difference when his side goes head to head with United again, this time at Villa Park and live on 
"It is quite unique to play a team in the space of five or six days," Gerrard said when asked about facing United again in a few days
"The players have an opportunity to flip the mood, flip the feeling
 I am sure they are frustrated
 They played quite well and dominated large arts but with no rewards for the performance so they have an opportunity at Villa Park to straighten that out
"I am not disappointed in the performance tonight just disappointed we didn't take our chances and conceded a sloppy goal
"Manchester United visit Aston Villa in the Premier League next Saturday at 5
