I wouldn't call him the best coach in the world. He is definitely one of the best and that too, looking at his statistics (with Barca only). He hasn't proved himself with a medicore team yet. He lacks defensive vision, you saw yesterday, he played 3 defenders against Messi, Neymar and Suarez. He is know to acquire a team that is pretty much build up (both Barca and Bayern) and continue the success which eventually he is failing at Bayern. Remember, Bayern did Treble before Pep took over Bayern. From that perspective, I say he is unsuccessful and DOES NOT deserve to be call the best coach.
