Ole Gunnar Solskjaer continues to have injuries to deal with, but that didn't stop them in Paris. It did hinder them at Arsenal last time out as their away day invincibility slipped away, and Molineux is a tough place to go and play, especially if Romelu Lukaku misses out with a foot injury. Team selection will be key here but both teams will be as string as possible with the international break coming up soon afterwards, and both know this is a great chance to at least get to a final.
Possession was turned over, knock-downs were won and even when the game was decided and Swansea had all but offered their surrender, so United came back for more. By the end Anthony Martial, an effective substitute, had swept in the fourth and the afternoon felt very different.
Eric Bailly scores Manchester United's opener Credit: AFP Pogba looms over the every aspect of the game, the kind of player whose considerable presence must appear in the peripheral vision of just about every opponent when in possession of the ball. Between them, Pogba and Lukaku now have five goals in two games and it is Pogba whose personality seems to be key to this team — when he is confident and diligent, then so are United.
Mourinho did not feel that the decision of referee Moss, an official with whom he has history, to award the first yellow card was justified, let alone the second that never came.
Paul Clement could not bring himself to claim a missed dismissal either and he has more pressing concerns on his mind. Tammy Abraham, on loan from Chelsea, showed some nice touches on his first team home debut with Fernando Llorente still out, it looks like a tall order to ask the teenager to shoulder all the burden.
Clement also lamented the absence of the injured Ki Sung-yueng and yet he could make no guarantees about new arrivals before Swansea play Crystal Palace next Saturday. It might have been different for Marcus Rashford — who faded in the second half before eventually being substituted — if he had finished on 36 minutes.
Booed for his dive in the fixture at Old Trafford last season, he had torn through the Swansea defence only to poke a lame shot at Fabianski. Rashford has an urgency about him that suggests he knows that patience is limited, and he started strongly only to lose his way.
The challenge this season will be maintaining the freedom to his game that made him a success in the first place. He came off when Mourinho made his changes with 15 minutes to go, at a point when United had at times been on the back foot. Mourinho responded by bringing on Martial and then Marouane Fellaini into the midfield at the expense of Mata.
Swansea had coped badly with the tactical switch and the fourth transformed the scoreline into something much more painful for the home crowd, Pogba again involved before Martial cut onto his right foot and picked a spot in the corner.
Mourinho reminded everyone that United had won the first two games of last season and he did not have to add that they were nothing like title challengers come May. A certain confidence has returned to United that has not always been detectable in this team over the last four years.
