Liverpool manager Jurgen Klopp has said that his side's 4-3 victory over Borussia Dortmund at Anfield this evening showcased European football "at its best".
The Reds twice came from two goals down against the tournament favourites to seal a 5-4 aggregate win and book their place in the semi-finals of the competition, with Dejan Lovren netting the winner in the 91st minute.
Klopp admitted that he was at a loss to explain the match, which saw his side fall 2-0 down inside 10 minutes, but acknowledged that it will go down as another memorable European night at Anfield.
"It is difficult to explain. A wonderful, wonderful night at Anfield and to be honest the game was strange," he told BT Sport.
"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."
The draw for the semi-finals of the competition will take place tomorrow.
