Full-time: Manchester United 4-0 West Ham United


Pogba has his goal! Tight, slick passing all round from United with Martial sliding a pass inside to the Frenchman who has the room to carry the ball forward past some weary West Ham defenders and curl one around Joe Hart from outside of the box.

Martial caps a wonderful day at the office for United. It's lovely intricate stuff as Lukaku feeds Mkhitaryan who slides a perfectly measured ball through for the Frenchman who has timed his run perfectly. His first touch is perfect, allowing him to open his body up and slot past Hart.

Five minutes remain at Old Trafford.


If Zabaleta thought things were going to get easier after Rashford went off, he'd better think again. Martial picks up from where his teammate left off, racing down the left flank before cutting in and lifting a delicate ball in which Lukaku is inches from connecting with.


And here's one for West Ham with Aaron Cresswell replacing Masuaku.


Or maybe not. United's next change sees Anthony Martial coming on for Rashford.


TV microphones have just picked up Mourinho bellowing 'JESSE', so we might be seeing Lingard in the near future.


Here's United's first change, Juan Mata makes way for Marouane Fellaini.

Romelu Lukaku

18 minutes left for him to claim a debut hat-trick.


United close again! Valencia is freed in acres of space down the right and lifts an inviting ball across to Blind, who has raced into the box. He watches it fall out of the air and fires his volley into the ground, hoping the bounce will take it over Hart. It does, but it takes it just over the bar too.


Rashford a whisker away from making it three! Zabaleta, on a yellow card, is now terrified of putting a challenge in on the youngster who is racing at him at pace again. Rashford cuts inside past him and lets fly with with a vicious curling effort that comes back out off the inside of the post!


Magic from Mkhiatyran as he races through the middle, riding challenges all the way before driving a shot on goal that is well saved by Hart.


Sakho can't get contact on a ball whipped across the United box and the home side counter through Rashford down the left. He cuts inside and finds Mkhitaryan, who slides it onto Lukaku who is momentarily unmarked. He winds up to shoot but Zabaleta makes a vital block to deny the Belgian a debut hat-trick.


Here's a change for West Ham, 18-year-old Declan Rice comes n for Noble.


Off the bar from Arnautovic! Noble floats a hopeful ball into the box where the new Hammers signing is being marked by Blind, a major mismatch. Arnautovic easily outjumps him and nods the ball on but it bounces off the top of the bar and out.


United have the ball in the back of the net but it won't count. It's lovely build up as Rashford slides a pass through the legs of Fernandes into Mata but the United striker is offside as he gets the ball back. He slides it across goal for Mkhitaryan to tap home from three yards out but the flag has long been up.


He's got another one! Mkhitaryan whips in an inviting cross and Masuaku is caught the wrong side of Lukaku who rises above his marker with ease to nod into the far corner.


Goal! Manchester United 2-0 West Ham United (Romelu Lukaku, 52)


Oooof. Zabaleta, backpedding with Rashford bearing down on him, steps across the youngster and blocks him off unceremoniously, sending him to the turf. United free kick.


Huge chance for United to make it two. Pogba frees Rashford down the inside left with a sumptuous pass right into his path. Rashford's pace leaves Reid for dead and he opens up his body and shapes to bend one into the far corner, but ends up firing well wide. Poor effort.


And we are back underway for the second half at Old Trafford.
