Extra-time being played in the match between Sevilla and Athletic Bilbao.

But we know that Shakhtar Donetsk and Villarreal are, like Liverpool, into the last four after both teams scored six goals over the two legs.

Anything for Liverpool to fear?

Liverpool manager Jurgen Klopp speaking to BT Sport: "My right arm hurts - I don't know why or who hit me. It's a great night not to forget.

"We fought back like devils and it is deserved. A little bit lucky."

Liverpool boss Jurgen Klopp on BT Sport: "It is difficult to explain. A wonderful, wonderful night at Anfield and to be honest the game was strange.

"When we brought Daniel Sturridge and Joe Allen on we gave them the message, 'we have to show character.' I don't care if we lose, we have to show them and we did even more. This is European football at its best. It's hard to believe. Congratulations to all of the lads.

"At half-time it's difficult to stay brave but we agreed that the we had to go the hard way. It is a game that all fans - even not of Liverpool or Dortmund - can say, OK, football is a nice game."

Liverpool have conceded three goals - Klopp knows they will concede, he said Dortmund would score.  You cannot write this kind of stuff, it is impossible."

A fan called Michael says 'this is the greatest day of my life!'

I thought he may have overcooked it a touch - Liverpool haven't won it yet - but he then reveals that he's just had his first child. He's keen on calling it Dejan...

Dejan Lovren really putting the game in context there...

Liverpool striker Divock Origi speaking to BT Sport: "We can tell our children and grandchildren. When we scored the first goal we felt it was going to be a special moment."

Reds matchwinner Dejan Lovren: "It's an amazing feeling. It's one of the best games in the last two or three years. We never stopped believeing in ourselves. It is a great effort from everyone. We didn't expect we would start like we did."

Liverpool defender Mamadou Sakho: "The most important thing was the team played with heart and the fans never leave us. It's a win for the Liverpool country."

What odds would you have given me on Sakho and Lovren being the match winners?!

Sometimes, football is just brilliant isn't it? 

It doesn't matter who you support, what you do, even if you are really a football fan - nights like that are special.

"Just the sheer bloody-mindedness and determination of the Liverpool players who played tonight has been absolutely magnificent."

You've got me there. In the words of the great Murray Walker, "I don't make mistakes. I make prophecies which immediately turn out to be wrong."

"For Liverpool to get themselves back in this game, let alone win it, is a fantastic achievement."

The Liverpool players link arms and salute the Kop as Jurgen Klopp looks utterly delighted. This is one of those nights.

Klopp approaches the Dortmund fans now and they greet him in kind. A superb touch that.

"Wow! What makes it even more dramatic and fantastic is the way that Liverpool didn't start the game. To be completely outplayed for the first half and then do that...

"It is the comebacks of all comebacks."
