'We are f***ing mentality giants' - Klopp hails titanic Liverpool comeback

The Premier League side trailed the Liga champions 3-0 from the first leg at Camp Nou last week but doubles from Divock Origi and Georginio Wijnaldum helped them overturn the deficit at Anfield.

Klopp was left lost for words by the performance and admitted that he would have written any other team off given the task on their hands, not least preventing "the best team in the world" from netting a potentially pivotal away goal.

"It was really, the whole performance, the whole game, was actually too much. It was overwhelming," he told BT Sport.

"I said before the game it was impossible but because it's you I said we had a chance. I've watched so many football games in my life and I don't remember a lot like this, playing against the best team in the world and you're not allowed to concede. Winning is already difficult but winning a clean sheet. I don't know how the boys did it.

"It's 10:10pm and the children are in bed. These boys are f***ing mentality giants. Unbelievable. Fine me if you want!"
