Mo Salah has won almost every induvidual away he was eligible for and the team from Merseyside have booked their place in the Champions League final.
"What the boys have done this season is unbelievable," Klopp said to 'Sky Sports'.
"We've had so many injuries to key players. You saw today (Adam) Lallana come on, we missed him the whole year, I can't believe it, how we could achieve something like this without a player like him.
"(James) Milner couldn't play today, and Hendo [Jordan Henderson] and Gini (Wijnaldum) have 9,000 games in their legs, the three up front try everything, Dom Solanke without match time doing things like this. It's an unbelievable achievement. I am really proud of the boys.
"It's a nearly perfect season for us. We have had no chance to challenge Manchester City so then all you can really go for is a Champions League spot."
