Keita signed a five-year deal with the Reds last month, and will make the move to Merseyside on July 1, following his final season with Leipzig.
Liverpool are believed to have paid the Bundesliga outfit a £7 million premium on top of the £48 million release clause that would have come into effect next summer.
But despite that lofty valuation, Keita is still widely considered an excellent acquisition, with Klopp revealing the positive response the signing has garnered.
“I have contact with a lot of people in Germany. I’ve never had so many congratulations like when it went public that we signed Naby,” he enthused.
“Because he’s the player of the league, that’s how it is. Last year together with Thiago Alcantara, who played outstanding for Bayern, he was the flier.
“He’s been doing that already for two or three years in different leagues.
“He’s still a very young boy—that’s really good news. OK you have to wait, but sometimes you have to wait for the really good things.
“I have no problem with this, I would have preferred another situation, but that’s not a problem!”
