As Paul Scholes and Rio Ferdinand slope off into the night it's time for us to bid you farewell.
Catch up with the report and reaction here - and we shall see you tomorrow night for the FA Cup!
If Klopp asked us to walk on water, the Kop would try. Boom!
A fitting way to end his time at United, praising the atmosphere Liverpool created. Shameful.
Liverpool boss Jurgen Klopp: "It was good. No matter how you play against Manchester United it is always difficult to make chances. We could have scored more goals in the first half, but that's life.
"Scoring the second goal was very important. We know it is only the first leg but we needed to win it and we did. We are in a good position now, we want to go through to the next round.
"The atmosphere tonight was unbelievable. Really great and I want to say thank you to everyone that was involved. That was Liverpool how I knew it before I came here."
Liverpool manager Jurgen Klopp: "It was not too bad to be honest! We were really good from the first second, everything was there but we could have scored more. That sounds crazy I know but we had the chances. In the end, 2-0, if you said this before the game of course I take it. But it's not over, we go to Manchester but it's the best thing we could do.
"It was a great atmosphere, I am so pleased for all of the people who have had harder times with us this season. Tonight was the first part of paying them back.
"We gave them no time in any situation. I'm really pleased for Joe Allen, he has not been playing and I don't like this but he showed how strong he is."
Chris Byland: LVG should probably read about the history between United and Liverpool before he goes round praising them and their fans...
Nikhil Jadva: Was LVG watching the same match as everyone else? Fellaini was absolutely appalling.
"The fairytale has gone," say Rio Ferdinand on BT Sport as the pundits continue to digest that Manchester United performance.
What do we think?
Lewis Cameron: some players make others around them better. Fellaini makes everyone else worse. United so much better with younger players.
More from Paul Scholes on BT Sport: "Manchester United have spent £300m and they are sixth in the league, they have ended up in the Europa League. They should be competing with Barcelona, Real Madrid and Bayern Munich.
"Manchester United didn't need a new philosophy. They had one for 20 years which worked."
Louis van Gaal praising the Anfield atmosphere - dangerous ground for a Manchester United manager!
Manchester United manager Louis van Gaal: "I have to say that Liverpool created an atmosphere that was fantastic. They played very good in the first half and we could not cope with their pressure. David de Gea was fantastic. But we had a cheap penalty and in the second half we changed the shape. We had much more contribution to the game but we didn't create enough.
"They scored another cheap goal, he was offside, and that is difficult. Losing 2-0 is a difficult result for us but we have to create an atmosphere like that next week.
"Liverpool deserved it. I haven't seen [the incident with Marouane Fellaini] but I have to say that Fellaini was one of the best players on the pitch."
Still no Manchester United reaction yet...
When I saw Fellaini in the starting line up, I just let the missus put on the only way is Essex.
I mentioned it earlier on but I wonder if Michael Carrick will be sent out to face the cameras. He seems to be the party man for these events...
When Gary Neville gets round to reading about how Manchester United got on at Liverpool tonight he'll have already digested one away defeat - his Valencia side were beaten 1-0 by fellow Spanish side Athletic Bilbao.
Villarreal (the fourth Spanish team in the competition) beat Germans Bayer Leverkusen 2-0 at home, while Sparta Prague led Lazio but were pegged back to 1-1.

Liverpool captain Jordan Henderson: "The fans were brilliant, electric. That gave us a great boost. De Gea made some good saves, we created a lot of chances and we felt we could be two or three up."
Adam, Mansfield: Given their last two results and next three fixtures, when was the last time Man Utd lost five games on the trot?
West Ham in the FA Cup at home, Liverpool at home (Europa League again) and Manchester City away in the league up next for Louis van Gaal's side..
The Manchester United fans are still all in their seats at Anfield. There's an ill mood brewing - and that's just in the TV studio.
Former Manchester United captain Rio Ferdinand says on BT Sport that Liverpool overran United throughout and says that the home side 'played like United used to.'
"It was shambolic. So bad," says Paul Scholes.
I'd like to play Scholesy at poker. He can't keep his feelings in. Absolutely fuming...
Gideon Marcel: The only thing #Van Gaal has which David Moyes lacked is a note pad.
Mr Lamide: Waiting for Van Gaal to analyze how we only gave few chances away and how Liverpool scored with their only shots on target.
EPM: Hope we don't rue those missed chances,good performance Liverpool. Fancy us to score at OT kudos to De Gea world class #BBCFootball
The second leg is next Thursday, by the way, so not long to wait. In between Manchester United face West Ham in the FA Cup.
A key few days in their season?
The TV replays have just shown an incident that I - and the officials - missed just before full-time. It looked like Marouane Fellaini deliberately swung an elbow into the face of Emre Can. More trouble to come?
Former Manchester United midfielder Paul Scholes on BT Sport: "Liverpool had a way of playing. United - I didn't have a clue what they were trying to do."
Ex-Everton and Republic of Ireland winger at Anfield for Radio 5 live
"This is a huge game to win, and Liverpool deserved this victory. Two-nil and could it have been more? I would say so. The home side dominated much of the game and created far the better chances."
James Carter: Absolute shambles! I have defended LVG for so long but it gets worse and I see no light as we're left in everyone's shadow
MakSteel: How will LvG survive this. We have no lower league opposition left to play to save his job.
Paul Humphreys: Pathetic showing. I cant even remember having a chance. Well deserved loss and could have been worse
Jurgen Klopp enjoyed that, it's fair to assume! His radiant smile beams down from on high as he struts onto the pitch to engage with his players one by one. The away end are locked in angry chants - not sure if they are aimed at their own or their rivals though.
Liverpool win the first European meeting of these two giants. And bar a 10-minute spell after half-time it was easy...
Unless they can muster something in the final few minutes, Gary Neville's Valencia is on course for a 1-0 defeat at Athletic Bilbao, Raul Garcia's strike is the difference.
Meanwhile, Cedric Bakambu's two goals has Villarreal in control at home to Bayer Leverkusen while it is currently 1-1 between Sparta Prague and Lazio.
There are two minutes added on.
James Foster: Seeing Van Gaal win 5-1 with Holland against Spain really gave me a lot of false hope that didn't last as long as I wanted
Charlie Fox: Carrick at centre half Martial at left wing Fellaini your creative hub in midfield. Something wrong in all this surely
The Michael Carrick centre-half experiment may be short-lived. He's toasted for pace by Divock Origi and has to stretch to clear out for a corner. Looks like ending at 2-0 though...
BBC Sport chief football writer
"Red smoke is swirling around Anfield and The Kop is in full cry as Liverpool continue to over-run Manchester United.
"United have been so thoroughly dominated that we are coming up to the last 10 minutes and they have to create a real chance."
That's what he's there for! Bastian Schweinsteiger has room to swing in a cross and it's a good one, Marouane Fellaini beats Dejan Lovren easily and flicks his header wide.
Roberto Firmino, who looks more like a player every week, comes off to a huge ovation at Anfield. Divock Origi is on in his place. PACE.
Nathan: Just when you think Van Gaal is improving tonight happens...
Peter: De Gea didn't deserve that. Terrible defending by Carrick and I cannot see United score three.
Adam Lallana has had a very good game tonight as he skips away from another challenge in the centre circle for Liverpool. United are nowhere near out of this tie of course, and an away goal in the last 10 minutes could even make them favourites.
