After a lukewarm first half with a well-taken goal on the stroke of half-time, the Red Devils romped up the style late in the second half to score three goals in four minutes and secure back-to-back 4-0 wins in the Premier League 2017/18 season. Pogba, Martial and their effervescent summer signing, Lukaku were on the score-sheet yet again to drown a resilient Swansea side.
Paul Clement's side defended with grit and determination until they crumbled to a late onslaught by the visitors.
Here's how each player fared in the game.
Swansea City
Lukasz Fabianski - 4.5/10
Fabianski was mostly untroubled in the first half and was unlucky to concede the first goal after making a fine save from Pogba's header which came off the bar. As the Swans completely collapsed late in the second half, there was little he could do to save them.
Federico Fernandez - 6/10
Fernandez was Swansea's best defender in the first half and did a solid job of tracking and keeping Lukaku in a tight spot. His clearances were on point and kept the back three organized. However, he was slightly at fault for Bailly's opener and along with the rest of defence, was totally swamped by the resurgent United attack late in the game.
Kyle Bartley - 4/10
Bartley put in a good shift the first half but should've taken the chances he got from the set-pieces. Even he couldn't do anything about the 3 late goals from the visitor's side.
Alfie Mawson - 4.5/10
He was pretty decent in defence but was largely troubled by Rashford's pace throughout the game, almost gifting him a chance which the latter nearly scored of. Collapsed in the second half as part of the back three especially when it came to tracking Pogba for the third goal.
Kyle Naughton - 5/10
Playing at right wing-back in the new formation, Naughton barely made any forward runs throughout the game. His long balls were haphazard and had to largely stay in his own half for extra defensive duties.
Martin Olsson - 5/10
Olsson was slightly better than his wing-back partner but even he was wasteful in attack. Almost had a great chance from an overhead kick in the first half. A couple of his interceptions were vital to cut off United's attack in the second half.
Leroy Fer - 4.5/10
Fer had a forgetful time in the middle of the park and was quite reckless in his challenges as his cumulative fouls on Matic and Blind got him booked early in the second half. The attacks he started barely came to any fruition and he clearly needs some time to adapt to the new formation.
Thomas Carroll - 6/10
Thomas Carroll was the most effective midfielder on Swansea's side with his tireless running and vital long passes. He was frustrated at his teammates and couldn't influence the outcome as the game went on.
Roque Mesa - 5.5/10
An above-average debut game for the new summer signing from Spain, though it was evident he will take time to adjust to the pace of Premier League. Even though Mesa couldn't influence the proceedings much, he put in a decent shift at rotating the ball defensively.
Jordan Ayew - 6.5/10
Ayew was the life of all Swansea attacks and even hit the post early on. He was always threatening the United defence with his trickery and hold-up play and could've had a couple of assists to his name. His dribbling was on point and he was unlucky to not earn a goal for his efforts.
Tammy Abraham - 4.5/10
Even though Abraham worked hard at holding up the ball and linking up with Ayew, he was wasteful with the few good chances that did come his way. More can be expected from the 19-year-old in the games to come.
Substitutes :
Wayne Routledge - 5/10
Came on in the second half but was nowhere to be seen as United tightened the screws.
Luciano Narsingh - 5/10
Came on as part of the first double substitution from the home side and even though he tried to link up with his fellow attackers, he could not penetrate United's back four.
Oliver McBurnie - N/A
Came on too late in the game to influence anything.
Manchester United -
David De Gea - 6.5/10
The Spaniard wasn't troubled much throughout the game but was nearly caught out when Ayew's mishit stuck the post. The few shots that did come his way were handled quite easily.
Daley Blind - 7/10
Blind was nearly caught out on his side in the first half but recovered well at the restart. Attack-wise, he gave an inch-perfect delivery in the build-up to the first goal but was largely wasteful running forward on the left flank.
Eric Bailly - 8/10
Even though Bailly was found out a couple of times early on in the first half, he recovered magnificently and made vital clearances. He was the hero of the first half, as his quick reaction in the box opened the scoring for United. An overall dominant performance from the Ivorian.
Phil Jones - 8/10
Phil Jones nearly scored himself by hitting the woodwork inside the first 10 minutes. He was very solid defensively and made crucial clearances. The Englishman seems to be making a strong case for himself as the first-choice centre-back for Mourinho's side this season.
Antonio Valencia - 7.5/10
A complete performance from the Captain today. He was solid defensively and his runs from the right side were threatening. His consistency from last season seems to be sticking around.
Paul Pogba - 8.5/10
In the first half, he lashed out twice and got booked on early on. To answer the boos of the Swansea fans, he rose high at the end of the first half to hit the woodwork which led to the first goal. He was instrumental in the dominant United counter-attacking in the second half and scored with a lovely chip and even earned an assist for the 4th goal.
Nemanja Matic - 8/10
Matic put in another brilliant performance in the middle of the park, dictating play with his effortless passing and breaking up opposition play with his crucial interceptions. In a largely forgetful first half for United, he seemed to be the only one whose performance hadn't dropped a notch from last week's display against West Ham. He kick-started all United attacks and his positioning helped Pogba thrive in the second half.
Marcus Rashford - 7.5/10
Rashford was at his usual lethal best and continuously wrecked havoc on both the wings with his deadly pace. In spite of that, he missed a couple of good chances. His antics in the first half kept United's attacks alive. More to expect from the youngster in the games to come
Henrik Mkhitaryan - 8.5/10
The Armenian was largely invisible in the first half and couldn't get involved in the attacks, much to United's frustration. A complete turnaround in the second half saw him at the helm of all attacks, as he linked up wonderfully with his teammates to clock two brilliant assists, two games in a row.
Juan Mata - 7.5/10
Mata put in some really good set piece deliveries and crosses, with Phil Jones nearly scoring from one of them in the first half. His off the ball movement troubled the opposition but he couldn't muster a serious threat for most parts of the game. He was substituted off with nearly 20 minutes left in play.
Romelu Lukaku - 8/10
Lukaku was barely influential in the first half and the one chance he did get early on was wasted too easily. He was largely quiet for most of the second half too until a pocket of space opened up and he finished the game with a well-taken left-footed shot. Linked well with his fellow attackers to finish off the game.
Substitutes:
Marouane Fellaini: 7/10
Fellaini came on at the 75th minute and provided extra defensive cover to start the goal romp which led to 3 goals in 4 minutes. His presence helped free-up Pogba further up.
Anthony Martial: 8/10
Martial had an immediate effect when he came on and started troubling the defenders with his trickery. He was involved in the buildup to the second goal and got himself on the scoresheet for two games in a row, scoring the 4th and final goal for the visitors. Made a strong case for himself to start the next game.
Ander Herrera: N/A
He came on too late to influence the proceedings.
