Trailing 3-0 from the first leg, Liverpool did the unthinkable as doubles from Divock Origi and Giorginio Wijnaldum gave them a 4-3 aggregate victory at Anfield, becoming only the third side in the competition’s history to overcome a three-goal deficit in the semi-final.
Klopp was almost lost for words as he tried to express his feelings after the game, admitting we may never see such a game again.
He told BT Sport “The whole game, the whole performance was too much. It was overwhelming. I watched in my life so many football games but I can’t remember many like this.
“Winning is already difficult but winning with a clean sheet – I don’t know how the boys did it. I saw James Milner crying after the game on the pitch, it means so much to all of us.
“There are more important things in the world but creating this kind of atmosphere is so special.
“It’s 10 past 10, most of your children are probably in bed but these boys are f*****g talented giants. It’s unbelievable. Fine me if you want. I’m not native so I don’t have better words for it.”
Klopp then said in his post-match press conference that he had told his players he “didn’t really believe” they could turn it around, but that the character in the side eventually gave him faith.
“I said it before [to the players], I don’t really believe, but because it’s you I believe. Their heart is unbelievable. And I am really proud to be in a job with this team.
“I will remember it forever 100 per cent. I don’t know if it can happen again and I don’t know if it happened before.”
Liverpool will now face either Tottenham or Ajax in the final, and Klopp says his side are looking to erase the memories of last season’s final defeat by Real Madrid in Kiev.
“[After] last year, we felt we have to go back. We cannot let it stand like this. Now we go back and we have another chance.
“Winning against Barcelona is obviously one of the most difficult things in world football. We had to score four goals and not concede and that made it more difficult.
“We didn’t think about [winning] it, if I am honest. We tried to think about the good things we did in Barcelona and go step by step.
“The mix of big heart and football skills was unbelievable. I said it so often now, the thing that made it so possible.”
