A rare clean sheet win for Liverpool and Jurgen Klopp goes over and plants a kiss on David Wagner.
Read a match report of this game on the BBC Sport website.
Joel Matip heads over the bar from a corner. He was unmarked and should have done better.
Liverpool are hunting a fourth goal.
They're finishing the game with Emre Can and Doninic Solanki on the pitch. Mo Salah and Daniel Sturridge have been taken off with a view to Wenesday's Champions League match with Maribor.
A rare clean sheet for Liverpool?
Three minutes to go plus added time.
Liverpool are minutes away from climbing three places up the table to sixth spot. This has been a good day for the Reds.
Mahamud: Really wanna know what is behind Firmino's weird celebrations...
Desmond Oguda: Get in Firmino! And what's that celebration about?
It's all smiles for Liverpool as Georginio Wijnaldum marks his return to the side with a terrific finish inside the area following another delicious move.
You wouldn't bet against the Reds from adding another before the finish.
Huddersfield have just had their first shot and we're inside the final 20 minutes. Tom Ince sends a free-kick over the wall and well over the bar.

It's corner after corner for Liverpool. They are chasing more goals and they look like a completely different team in this second half.
They are in the mood.
It's Champions League night at Anfield on Wednesday so Jurgen Klopp is likely to make full use of his bench.
Here comes the first change. Goalscorer Firmino gets a standing ovation as he makes way for Alex Oxlade-Chamberlain.
Now Anfield really would erupt if the Ox could join the goalscoring party.
It's taken a while but Liverpool are turning on the style now.
A shot on the turn by Mohamed Salah whistles just wide of the post.
It's one way traffic. Damage limitation for Huddersfield.
It'll require an effort even more heroic than last week's win over Manchester United for Huddersfield to get back into this.
This is much more like it from Liverpool.
They are a completely different animal since taking the lead and Roberto Firmino doubles the lead after attacking a James Milner corner to head into the bottom corner of the net.
The Kop is in full voice.
What do Huddersfield have in their locker?
The Terriers have done a sterling job frustrating the hosts but they need to go for it now they are behind.
That was Sturridge's first goal since the 4-0 thumping of Arsenal in August.
At last some quality!
It's a shocking mistake by Tommy Smith in front of The Kop who heads Alberto Moreno's pass straight to Daniel Sturridge who cleverly lifts the ball over the advancing keeper.
Anfield breathes a sigh of relief.
Huddersfield - whose touchmap is the right-hand graphic above - are yet to have a touch within 15 yards of the Liverpool goal.
The Reds - on the left - have been busier but, as so often, this season they have not carved out enough clear-cut chances.
Dominic Solanke, Alex Oxlade-Chamberlain and Marko Grujic are the attacking options on the home bench.
This game can only get better. Back under way.

Jurgen Klopp was singing Mo Salah's praises after he scored that penalty which sent Egypt through to the World Cup.
You could hear supporters wondering why Salah took that penalty in the first half though, especially with James Milner and Roberto Firmino on the pitch.
I don't quite understand what this graphic means, but it boils down to Mohamed Salah's penalty being pretty awful.
According to the xG experts it was in the worse 10% of penalty kicks in terms of placement.
Liverpool have now missed 34 Premier League penalties - no side has missed more in the competition. (Arsenal also 34).
David Wagner 1-0 Jurgen Klopp.
Typical of Liverpool's day.
Mohamed Salah spot kick is brilliantly beaten out by Jonas Lossl. The rebound falls straight to Jordan Henderson but the Reds captain clips the post with a first time shot.
Scenes in the Huddersfield end.
Foul by Tommy Smith on Roberto Firmino. Good spot by referee Kevin Friend? There's no doubt Smith was tugging Firmino's shirt but there seemed to be a delay before he pointed to the spot.
Great chance for Liverpool to bring this game to life.
The positives for Jurgen Klopp is his defence has not conceded.
The negatives? His side are way too slow, lacklustre, subdued and look, well, awful.
Half a chance for Liverpool as James Milner tests Jonas Lossl from distance.
This has been all too easy for Huddersfield's defence.
The visitors have been forced into an early change after Rajiv van La Parra suffers a knock and is unable to continue. Elias Kachunga is on.
Chris Lowe is off the pitch with nose bleed. It's a quick change of shirt for the Huddersfield defender. Liverpool are looking so ordinary.
Was that a chance?
Mohamed Salah finds Daniel Sturridge in the six-yard area but the Liverpool striker has his back to goal and is surrounded.
Moments later Salah tests Jonas Lossl for the first time. It's straight at the Huddersfield keeper. Comfortable.
This is rather too pedestrian by Liverpool. Where's the tempo? The energy? The creativity?
No shots on target by either side.
Tom Ince's Liverpool career consisted of one appearance in a League Cup defeat to Northampton Town.
He's putting himself about at Anfield as though he has a point to prove.
Salah is on the attack inside the Huddersfield half when Ince puts an end to it with a super challenge.
It's pretty dull so far which will please David Wagner no end.
The visitors have plenty behind the ball and are well disciplined which is making it harder for the Reds to break them down.
It's Wagner 1-0 Klopp in terms of the tactical tussle at the moment.
Almost the breakthrough for Liverpool.
Daniel Sturridge meets James Milner's cross at the back poss but his attempt bounces over the bar.
The Reds are stepping it up.
Three goals already at The Hawthorns - Manchester City are 2-1 up against West Brom - but we're still awaiting a first decent chance at Anfield.
Georginio Wijnaldum is back on the pitch but he doesn't look comfortable.
The Reds are already without Philippe Coutinho, while Dejan Lovren was injured in the warm-up.
Georginio Wijnaldum is down receiving treatment after an aerial challenge. Not another Liverpool injury?
Huddersfield are inviting danger by giving the ball away inside their own half.
Alberto Moreno whips in a delicious cross which is just about stabbed clear by a blue and white shirt.
Liverpool are enjoying lots of possession but that means little unless you find the net, right?
Huddersfield are passing the ball around nicely. The Terriers win the game's first corner as Danny Williams forces an error from Alberto Moreno, but Joel Matip heads clear.
Daniel Sturridge needs a goal and he's already had the ball at his feet inside the Huddersfield penalty area but it's hacked clear before the England striker can cause any damage.
How will that late change impact Liverpool?
We're under way at Anfield.
BREAKING: Dejan Lovren has been injured in the warm-up and Ragnar Klavan starts for Liverpool.
Every player is sporting a shirt featuring a poppy and there is now a minute's silence as this is Liverpool's last home Premier League match ahead of Remembrance Sunday on 12 November.
