The Manchester City boss has won titles in England, Spain and Germany, and his famous 'tiki-taka' style has been replicated all over the world.
And Valdano thinks the Catalan has a "God-like" impact on the beautiful game.
"Klopp has a strategist, which is Firmino, and two bullets, Mane and Salah. The novelty is that the three play very close, they spread the field from one end of the area to the other.
"That said; nobody has influenced world football more than Guardiola.
"Any third division team opens to the centre, pulls the sides forward, asks for the ball at the back and goes towards the middle to create numerical superiority.
"It's very interesting that we are not in the dynamics of the old days, when a very good team ended up beaten by a team from a very speculative school of thought. You don't see many teams waiting and throwing balls forward.
"The result is God-like. There is a demand for the show that Guardiola set up, which, in some way, has modified the demand of people towards the football they see."
