Full-time: Swansea City 0-4 Manchester United
Three minutes of time added on at the Liberty Stadium.
Martial 's cool finish means it two in two for him. The same applies for Pogba, while Lukaku has three in two.
Amid all that, Ander Herrera has come on to replace Mkhitaryan. The Armenian sometimes struggled to impose himself on the game today but he leaves the pitch having laid on two brilliant assists.
I'm struggling to keep up here. Just like he did last week, Anthony Martial is off the bench to score late on. Racing towards a weary Swansea backline, the Frenchman cuts inside from the left, drifting across Mawson before coolly sliding into the far corner out of Fabianski's reach.

Two in two minutes! Mkhiatryan is again the architect, racing down the inside right channel before sliding a ball through for the overlapping Pogba, who cuts inside to brilliantly chip over the onrushing Fabianski.

Lukaku settles it for United! Martial has the Swansea defence backpeddling, drawing three defenders in on the edge of the box. One of them manages to get a foot to it but Mkhitaryan slides a brilliantl ball through for Lukaku, who is unmarked in the box. One on one with Fabianski, he slams it home.

Just over 10 minutes remaining at the Liberty Stadium. United are comfortable enough, but could definitely do with another goal to kill this off.
Pogba takes it but he can't keep his effort down. Here come two changes for the away side, with Mata and Rashford making way for Marouane Fellaini and Anthony Martial.
Blind smashes a shot wide but play will be pulled back after a wild lunge from Fer trying to close down his fellow Dutchman. It's a booking for Fer and a free kick for United in a dangerous position.
Hernandez threatens to leap onto Carroll's delivery but it comes off Matic and goes out for another corner.
Anthony Martial looks like he is about to come on for United. Swansea meanwhile have a corner kick.
Woeful from Mkhitaryan. Rashford cuts inside and picks out the Armenian who has time to work the ball onto his right foot and shoot from just outside the box. He slices his effort however and it sails well wide.
First change for Swansea, Luciano Narsingh is onto replace Mesa.
Excellent from Ayew who skips around Valencia and slides an inviting ball across goal but Abraham isn't live to it with Blind able to usher the ball out for a goal kick.
Very cool defending from Jones. Ayew manages to slip a ball through for Abraham inside the box but the United defender steps in front of him and calmly passes back to De Gea who clears.
Mkhitaryan tries his luck from range, pinging one towards the far corner but a deflection takes it wide. Another United corner.
Olsson makes an overlapping run out on the left and whips in a cracking pass towards Abraham, who can't keep his header down and knocks it over the bar.
Swansea have shown a bit more life in the last few minutes but you can tell they have a new partnership up front. Jordan Ayew and Abraham don't look in sync yet, making the same runs and getting in each others way, making life easy for Bailly and Jones.
Mata does will to pick out Rashford in space, with the forward nipping inside his man looking to find space to shoot. He finds a few inches and lets fly, but again it is straight at Fabianski. His shooting has been pretty poor all afternoon.
All United so far in this half; Swansea have been pinned in their own half with the away side testing that backline with crosses into the middle looking for Lukaku.
