Jurgen Klopp thought Liverpool had a “death sentence” after the first leg of the Reds’ Champions League semi-final with Barcelona last season.
Barca had won the first leg comfortably after Lionel Messi’ double and Luis Suarez’s strike handed the Catalan side a 3-0 advantage.
The Reds returned to Anfield a week later to record a famous 4-0 win, thanks to Divock Origi and Gini Wijnaldim’s braces, to progress to the Champions League final.
Klopp’s men would go on to lift their sixth European Cup after they beat Tottenham at the Wanda Metropolitano in Madrid.
But the German admitted that despite his supreme confidence in his side he wouldn’t have put money on them to progress.
“The victory against Barcelona. It was the outstanding moment for sure,” Klopp told FIFA. “A lot of experts, myself probably included, wouldn’t have bet money on us.
“Because being 3-0 down against a team with Messi, Suarez and all those players looks like a death sentence. We didn’t believe we’d win, we just knew we had a chance, and we believed in that chance.
“It was massive. The support we had in the stadium. Looking back, we could say we won the Champions League in that game. All of us will remember it forever.
“I said [to the team], ‘I normally wouldn’t think it’s possible, but because it’s you, we have a chance’.
“That was exactly what I thought and what I felt. And from the first minute we were literally all over Barcelona.
“And at that moment, I thought ‘we are ready at least’, and it’s very difficult to cope with a team like us and the atmosphere in the stadium in moments like this.”
