Actually, Barca play that style for a lot longer. Also, it was Ronaldinho, Deco, Eto's with Rijkaard who made the Barca a success team. And if anything it was Rijkaard who brought Messi to the team and Xavi & Iniesta were focal point long before Pep arrived, so that's kinda BS. It was also obvious it'd be Messi to take Dinho's place once he leaves and it was not a rocket science nor a shocking discovery. Pep just took the torch.
No, his true level is winning domestic leages without competitions, because hey, those are just numbers

he should move to PSG next to dominate France and choke in Europe.

Which just shows how one-dimensional the guy is. He's clearly unable to switch the tactics and style of his play, so he needs a team full of Messi's and Iniesta's to 'shine'. Yeah, what a great coach.
Once one gets injured and it stops clicking then it suddenly becomes a Titanic. That's not a definition of a good coach, because hey, a good coach makes the best of what is given. Pep would be unable to coach majority of teams cause it obviously wouldn't click to fit his fucking tiki taka.
