Mane played his part in the Reds' Champions League-winning campaign, scoring four goals in the competition.
And the 27-year-old said Klopp is to thank for his brilliant form at the club.
Mane said: "He's a very special manager. He has a lot of qualities and distinctive characteristics, but what really struck me is that he's a really, really nice guy outside of football. His human side touched me, and that's really rare to find someone like that, especially in football.
“He's a coach who loves his players, he's there for them. At the same time, he gives them responsibilities. We, the players, are ready to do anything for him! We give everything on the pitch for him, whether it's in training or in a game, we give our all. He's a manager who makes you want to go to war."
