West Ham have been absolutely brilliant in the first 20 minutes. They have won every tackle and been right at it from the start.
The Southampton midfield has been missing.
Newcastle 0-0 Huddersfield
Huddersfield are beyond living dangerously now as Matt Ritchie weaves his way through a weak tackle to get into the goalmouth, and Jonas Lossl saves really well with his legs.

West Ham have started really brightly, pressing quickly, fans see players working hard they get on your side. It is just the start they needed. They now need to calm down, and control the ball and try to build on this.
Marko Arnautovic (17 mins)
It is two now! Southampton look an absolute mess, Championship bound on this display. They do not pick up Marko Arnautovic at all in the area, his header from Joao Mario's cross is really well saved by Alex McCarthy but the Austrian is able to slam home the loose change.
Arnautovic seemed to celebrate by shouting something at Mark Hughes in the dugout too...

Ah, it should be two!
West Ham carve the pliant Southampton rearguard open once again and Marko Arnautovic is clean through - wide!

The finish was fantastic.
Moyes will be delighted but Mark Hughes will be furious.
Southampton had a corner that they made a a hash of and that led to them conceding a goal.

Mikias: United playing attacking football? I don't believe it.
PJ: Just the flying start we needed! Romelu Lukaku with the finish!
Herbert: I'm fancying a Lukaku hat trick today, he's been lively so far.
Kiko Femenia (13 mins)
Bosh.
Kiko Femenia is loitering on the edge of the area and is in the perfect position to thunder home from a corner, which was taken short by Roberto Pereyra and whipped in by Jose Holebas.

The London Stadium erupts! But in joy, noy fury this time. Southampton lose the ball cheaply on the edge of the West am box and the hosts counter brilliantly.
It's pretty similar to one Ashley Barnes scored against them last time out as Mark Noble frees Cheikhou Kouyate down the right, he cuts it back to Joao Mario on the edge of the area, and he takes a touch before spanking a drive past Alex McCarthy.
Pick that one out!

Manchester United have started in style.
After putting the hosts ahead on five minutes, Romelu Lukaku forces Lukasz Fabianski into a low save.
And then Jesse Lingard does the same thing. Swansea are under pressure.

An excellent break through the middle by Brighton forward Jurgen Locadia, but he is off balance as he strikes a shot from range and it is easily dealt with. Wes Morgan is then booked for taking out Davy Propper.
West Brom 0-0 Burnley
West Brom make a decent break.
Jay Rodriguez's flicked header reaches Salomon Rondon, but the West Brom forward can only head at Burnley keeper Nick Pope.

Oddly enough it looked like Michail Antonio was labouring the first time he had the ball and he has tried to put all his power into that shot.
He looks like he is in floods of tears.

Jonjo Shelvey hits a free-kick into the wall and away as Newcastle continue to dominate the possession. Aaron Mooy thundered into the challenge.
West Ham 0-0 Southampton
Michail Antonio is in tears here, head buried in his shirt, as he limps off the field. He can't continue after pulling something.
On comes Edimilson Fernandes into midfield.
West Ham 0-0 Southampton
MIchail Antonio needs some treatment after hitting a shot which brings the Hammers a corner.
Romelu Lukaku (5 mins)
100 up!
Romelu Lukaku reaches a 100 Premier League goals with a left-footed shot into the top corner of the net, which looks like it took a deflection off Alfie Mawson.
Image source, ReutersWatford 0-0 Bournemouth
Bournemouth earn a free-kick from distance and Watford have everyone back.
It's whipped in by Joshua King and Nathan Ake heads it on to the bar! That was close.
There may have been a foul in the build up, though.
