Having been plagued by injuries since arriving two seasons ago, Guinean is finally beginning to show the form that prompted Liverpool to pay £52m for his services.
On the midfielder, Klopp said: “Of course injuries never help, and for sure they cost him rhythm. But people forget he started exceptionally well.
“Now he's completely settled in the squad, knows all the people around and that makes a big difference.
“In the last two years we didn't lose a lot of games, and as long as players are fit it is difficult to come in. Now it's all different, he is in a really good moment, fit as well and completely settled.
“So, very good football is possible when you have the skills of Naby Keita! High press, counter press, he was used to all these things from Leipzig. It's not that we have to adjust him.
“If you are not on your highest level, it's a constant inner fight with yourself. Because of injuries, he didn't have rhythm.
“Now, he has rhythm, and now we have to make sure he can keep that at least until the end of the season. Then we have another little break, then we carry on."
