That's all from me today.
- Kick-off - 15:00 GMT
- Huddersfield currently sit in 11th place
- West Ham are just two points above relegation
- Terrier's new signings on the bench
And it's all over.
David Moyes picks up his 200th Premier League victory on his 20th anniversary as West Ham go five points clear of the relegation zone.
Huddersfield remain four points clear but they have two tough fixtures to follow - away to Stoke before hosting Jurgen Klopp's Liverpool.
The stadium is half empty now. It's literally just the final whistle people are waiting for now. David Wagner will no doubt have his mind already on Huddersfield's trip to the Bet 365 Stadium.
On his 20th anniversary as a manager, David Moyes is about to become just the fourth boss to win 200 Premier League games.
He's standing alongside good company - Sir Alex Ferguson (528), Arsene Wenger (468) and Harry Redknapp (236.)
It also means the Hammers will go five points clear of the relegation zone. What a turnaround they have made!
Well, there's jeers and booing from the home supporters but that can only mean one thing. Marko Arnautovic is coming off.
He ran the show for West Ham today and after returning from injury, it's a wise decision from Moyes to bring him off before full-time.
A goal and two assists for Arnautovic - and my man of the match.
The home fans aren't content with sitting back though.
Some of them are getting off their seats and slowly making their way to the exits. It's not been an enjoyable second half for them at all...
The game has fizzled out a little bit in these last five minutes but that's understandable given West Ham's three-goal lead.
They look content to sit back for a bit and allow Huddersfield possession.
Just a reminder that Huddersfield have only lost at home on three occasions this season.
Their opposition? Manchester City, Chelsea and Tottenham. That puts into perspective what a great win this would be for David Moyes' West Ham.
Alex Pritchard has already made a good impression. He drives forward from midfield, earns a free-kick and almost scores on his debut!
He fires it low into Adrian and the West Ham keeper can only deflect it into the path of several players before it's cleared for another corner.
Skipper Tommy Smith is off and that means there's a second league debut for Huddersfield defender Terence Kongolo.
I'm sure he would have liked a better introduction than this but that's football...
Huddersfield are still fighting and there's a goalmouth scramble to head the ball in the West Ham box.
Pablo Zabaleta goes down clutching his head and his team-mates immediately call for medical attention.
He's fine though and he's already up on his feet and running around again.
Here he is.
It's Alex Pritchard making his league debut for Huddersfield. He signed on a three-and-a-half-year deal from Norwich City earlier this week.
I can't keep up! The goals are flowing for West Ham now.
I probably don't even need to tell you who was involved again as it was the same devastating duo...
Marko Arnautovic drives into the box, beats two players before being brought down. Manuel Lanzini is following up, takes it on his right and fires it past a helpless Jonas Lossl.
The hosts need to re-group. They have had an awful start to this second half and there's a danger West Ham could add more.
Mooy looks to create something but his cross is deflected out for a corner. The corner is over-hit and West Ham are eventually awarded a goal-kick.
It's that man Marko Arnautovic who is at the heart of everything yet again. He skips past Christopher Schindler then plays Manuel Lanzini in.
The Hammers midfielder cooly slips it past Jonas Lossl and it's as easy as that.
Goalline technology confirms the ball didn't cross the line by the way.
I know how much everybody loves talking about new technology in football...
How did that not go in?
Collins heads towards goal from the corner and it bounces dangerously in front of the goalline.
It ricochets off several players before hitting Cheikhou Kouyate and Aaron Mooy has to stick a foot out in desperation to clear the ball off the line.
I mentioned prior to kick-off that Arnautovic could prove to be a huge boost for West Ham today and he has done just that.
They really missed him against Spurs but he's looked lively today and that goal could see the Hammers move above their opponents in the Premier League table.
The Terriers have got to come from behind again here. But they have 41 minutes (or so) to do it so we could be in for a treat.
Wow! That was quick!
Out of nowhere, Arnautovic snatches away possession, drives forward then smashes his shot into the top corner.
I almost choked on my drink!
And we're off...
Thoughts on that first half? Let me know using #bbcfootball
Moyes says he wants his side to play "like Tottenham, like Chelsea" if he remains in charge beyond the end of this season.
The Hammers were more Sunday League than Premier League in a truly dire 0-0 draw with Shrewsbury last week but they have been much better today against a good Huddersfield side.
Moyes is dreaming big. And why not...
The tournament welcomes male, female and disability players across 18 categories, so there's a version for everybody.
There is the increasingly popular indoor game, Futsal, as well as walking football.
Here's Gary Lineker to tell you more ...
Not many chances in that first half for either side but Noble and Lolley were clinical. It's certainly competitive. Either team can win this. More of the same please!
The fans are enjoying this. Lolley finds himself on the ball in almost the exact same position from which he scored from just minutes ago and the crowd scream "shooooooooot" in anticipation.
He crosses it instead and eventually it runs away from Tom Ince.
It wasn't a bad corner either but Pablo Zabaleta uses his experience to calmly head the ball out of danger after it was headed on at the near post.
There were a few "ooh" and "ahh"s from the crowd but they're just getting a bit excited.
One minute to go of normal time in this first half. Will both teams settle going in all square at the break?
Huddersfield look like they want to add another and they have a corner.
Don't listen to me. West Ham have just conceded!
And what a goal it is too. Joe Lolley steps inside onto his left foot on the edge of the box and curls a wonderful strike past Adrian.
The home fans are getting anxious. They want an equaliser before half-time.
Christopher Schindler has had two glimpses at goal in the past two minutes (well, barely half-chances) but West Ham don't look like conceding.
A noticeable difference in the West Ham side since Moyes took over is their willingness to press the ball.
Noble's earlier goal was a result of that and Arnautovic has just busted his lungs chasing the ball around the back four.
It almost pays off as the Hammers win back possession in midfield but Huddersfield are alert and get it straight back.
There's not much between the two sides at the moment.
Huddersfield have enjoyed more possession but West Ham have started to grow into the game in the past 10 minutes.
They have another corner here too.
Oh, that was close!
Rajiv van La Parra fires a ball across the box and it wasn't far off two incoming Huddersfield players but it skips past everyone and goes out for a throw-in.
West Ham then look to counter-attack quickly and earn a free-kick on the edge of the box.
West Ham look confident now. Cheikhou Kouyate uses his strength well to shrug off defenders and escapes down the right.
His low cross is an awful one though and it trickles into the box, where Lossl is waiting to gather it up.
Lolley was furious with Lossl for that pass but the goalkeeper was equally as frustrated, gesturing his defender should have been more alert.
It was a risky ball to say the least...
Oh dear. It's an awful pass from goalkeeper Jonas Lossl to Joe Lolley and he's immediately put under pressure by Mark Noble.
The Hammers' skipper finishes it in style, smashing it into the top of the net. Game on!
David Moyes is on the brink of joining some decent company today.
He's one shy of becoming the fourth manager to win 200 Premier League matches, after Alex Ferguson (528), Arsene Wenger (468) and Harry Redknapp (236).
West Ham are four games without defeat in all competitions but so far they have struggled to create any sort of chance.
Lovely turn from Arnautovic. He is put under pressure from Huddersfield's midfield but he turns sharply, escapes several tackles and earns a free-kick.
This is better from West Ham. Arthur Masuaku and Manuel Lanzini are combining well down the left.
There's still not been a shot from either side yet though.

It wouldn't surprise me if David Moyes gets in one or two defenders in January, but only if the price is right. I also wouldn't be surprised to see Javier Hernandez go, because it seems like he's not part of Moyes' plans. So, if he goes they'll be another striker to bring in, too, it's going to be a busy window for West Ham.
