Manchester United 4-0 West Ham United: Premier League as it happened

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.

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.

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.

Half-time: Manchester United 1-0 West Ham United

De Gea denies West Ham on the stroke of half-time! Ayes feeds the ball into Hernandez who lays it off to Ayew right on the edge of the box. He hammers it towards goal but it is straight at the United goalkeeper who stays strong to bat it away.

Just the one minute of time added on at Old Trafford.

He's arrived.

Bailly picks up the first yellow of the match, sticking out a leg to halt Hernandez after the Hammers striker had turned past him.

If Antonio Conte is watching this, it won't be pleasant viewing for him. Nemanja Matic is looking fantastic out there, effortlessly winning the ball back before waltzing past three challenges with some incredibly slick footwork to gain a good 30 yards for his side.

Dream start for Lukaku! Obiang gifts possession in midfield allowing Rashford to gallop forward menacingly. He has Mata peeling off to his left but he instead picks out Lukaku's clever run through the middle with a sublime ball and the Belgian makes no mistake, smashing a precise effort in off the inside of the post.

Credit to Matic too; his interception freed Rashford to race forward and create the goal.

Goal! Manchester United 1-0 West Ham (Romelu Lukaku, 33)

West Ham finally break out of their own half through Masuaku who wins a free kick for his side when his trailing leg is caught by Pogba. The delivery however is an absolute waste of time however and it is cleared by he first defender.

Another chance passes United by. Mata again sneaks into the box, picked out brilliantly by a chipped pass by Pogba. He should probably take the shot on but instead looks for Lukaku again, failing to find him as Masuaku clears.

Rashford tries to twist and turn his way past a gaggle of West Ham players inside the box but doesn't get his shot away quick enough and settles for a corner. It comes to nothing however and United will try again.

Arnautovic briefly springs clear but the whistle had blown long before he thumped an effort against the post.

United just can't scramble it home! Mata initially forces a decent save out of Hart from a tight angle but the the Spaniard reacts quickest and forces the loose ball back across goal where Lukaku is lurking. Under pressure from two West Ham defenders, he can't force is goalbound and they can clear with some half hearted appeals for a penalty ignored.

Mata slips past his man with the cheekiest of nutmegs, cutting the ball inside to Rashford who is bundled over by Reid on the edge of the box but no free kick is given. West Ham aimlessly punt the ball clear and United coming again, with Mkhitaryan winning another corner.

It's complete dominance from United so far, even if that first clear cut chance still hasn't presented itself.

United are turning the screw a bit now. Lukaku does brilliantly to knock down a cross from Valencia but Mata opted not to gamble and run into the box for it. West Ham fail to clear their lines, allowing Mkhitaryan to pick up the loose ball in the box. Room opens up to shoot but he rushes it and fired wide.

Bailly brilliantly flicks on the resulting corner but Pogba doesn't react quickly enough to him and the ball sails past him with West Ham able to clear.

Old Trafford gets its fist glimpse of Lukaku in full flight as he wins the ball just on the edge of his own half, barging past one before bursting past Masuaku down the left. The West Ham does well to keep up with him but the Belgian striker wins a corner for his side.

Valencia is too busy arguing with the referee over a decision that went against him to notice he is miles out of position with West Ham advancing down his side of the pitch. The ball is cut infield towards Fernandes but he can't get his shot away in time and United clear.

Hernandez tries to turn Phil Jones just inside the centre circle and picks up a painful one for his trouble. West Ham free kick and their shiny new striker is able to run it off.

And United get their season underway at Old Trafford.

Almost ready for kick-off at Old Trafford where Javier Hernandez is pretty much guaranteed a warm welcome from everyone in attendance.

Ahead of kick-off, United have also announced their squad numbers for the coming season. There are no real surprises, with Romelu Lukaku no.9, Victor Lindelof no,2 and Nemanja Matic no. 31 as they wore during pre-season.

Andreas Pereira however has been moved from no.45 to no. 15, the clearest indication yet that he is part of Jose Mourinho's first-team plans this season.

He'll also wear 'Andreas' on the back.

Plenty of Lukaku shirts around Old Trafford today.

Jose Mourinho has made five changes to the side that lost to Real Madrid in the European Super Cup last week. Eric Bailly and Phil Jones were both suspended for that match but come back in today to replace Chris Smalling and Victor Lindelof. Daley Blind comes in at left-back instead of Matteo Darmain while Juan Mata and Marcus Rashford come into attack.

Ander Herrera misses out after struggling in that defeat to Real Madrid and Mourinho has opted to start with just two midfielders – a potentially fearsome duo of Nemanja Matic and Paul Pogba. Romelu Lukaku is supported by Mata, Mkhitaryan and Rashford so it is a fairly attacking line up from the United boss.

Jesse Lingard, Marouane Fellaini and Anthony Martial, reportedly wanted by Tottenham Hotspur, sit on the bench.

West Ham team to face Manchester United: Hart; Zabaleta, Ogbonna, Reid, Masuaku; Obiang, Noble, Fernandes; Ayew, Arnautovic, Chicharito.

BREAKING: Javier Hernandez makes his first West Ham appearance against his former club. Joe Hart, Pablo Zabaleta and Marko Arnautovic also given league debuts.

BREAKING: Romelu Lukaku and Nemanja Matic both make their Premier League debuts. Anthony Martial left on the bench.

Javier Hernandez, possibly the hardest man to dislike in English football, is back today. Let's look back on one of his greatest moments in a Manchester United shirt.

Jose Mourinho is relatively pleased with the squad he has assembled so far this summer, even more so with injury absentees at a minimum – by the club's standards anyway.

Manuel Lanzini will miss out today due to injury but amid ongoing speculation linking him with a move to Liverpool, Slaven Bilic is confident the Argentine will be straight back in his team when he is fit again.

Team news: West Ham

Defenders Winston Reid and Aaron Cresswell are also both available, although Michail Antonio (hamstring), Manuel Lanzini, Cheikhou Kouyate (both knee), Andy Carroll (groin) and Diafra Sakho (back) all remain sidelined for now.

Will we see Anthony Martial in the United starting XI today? On Saturday reports from France suggested United had turned down an offer from Tottenham Hotspur to sign the France international, having already rejected a bid from Inter Milan.

Team news: West Ham

Joe Hart, Pablo Zabaleta, Marko Arnautovic and Javier Hernandez are all in line to make their West Ham debuts this afternoon.

Team news: Manchester United

Ignoring the three still carrying knocks from the end of last season, United begin the season with no fresh injury problems with Nemanja Matic, Romelu Lukaku and Victor Lindelof all in contention to make their league debuts this afternoon.

Team news: Manchester United

Luke Shaw, Ashley Young and Marcos Rojo are all still unavailable due to respective knocks picked up at the end of last season but Jose Mourinho will have both Eric Bailly and Phil Jones at his disposal again after the duo missed the European Super Cup defeat to Real Madrid through suspension.

As Jose Mourinho kept reminding us last season, the second season is where he thrives. In his second campaigns with Porto and Inter Milan he won Champions League titles. Returning to Chelsea in 2013, he needed one test campaign before he got it right. His biggest test to date will be doing it with Manchester United.

The Portuguese has added three more players to the United squad, bringing the number of new faces picked by him personally up to seven. This is very much now a team in his image. With that, expectation is understandably high.

All eyes are likely to be on Romelu Lukaku today, the man brought into solve United's biggest problem last season; their inability to put clubs to the sword on their home turf.

But a familiar face in Javier Hernandez will be looking to steal the spotlight. The £16m signing from Bayer Leverkusen is expected to make his debut against the club that plucked him from relative obscurity in 2010 and provide West Ham with the reliable cutting edge up front they have been lacking for years.

All your team news is on the way.
