Klopp has praised his compatriot's influence at Paris Saint-Germain, who he took to the Champions League final last season.
"A fantastic, fantastic manager. You can see really his influence, it has changed a lot their style of play, how they play, different formations and stuff like that. I know a lot of people who have worked with him, they all are full of respect for him," Liverpool boss Klopp said of Tuchel.
"You cannot be in the Champions' League only because of spending money, that is not how it is. You need to have on the pitch a good organisation, because all the others we are not blind. We do our job as well and you need to have the right tools in the right moments and Thomas has that.
"It is not about being loved by your players, it is about they should believe they are the right decisions and the closer you are, the more they will think about it.
"We are not perfect, I am not perfect, Thomas is not perfect, nobody is perfect. It is easier if you like each other."
