It's true that Pep took the likes of Xavi, Iniesta etc. to the next level, but no one thought at the time that they were all elite, world class generational players in the making. It's easy to say in hindsight. Who knows, maybe Pep can elevate the likes of Hazard, Oscar, Zouma, Azpi, Courtois etc. (Just throwing some names out there) to the next level as well, whilst bringing through very talented youth players such as Boga, Musonda etc... And maybe give someone like RLC a proper breakthrough as well. I just think it's very difficult to tell, and a lot easier to say you disagree when you look at it in hindsight. However, you could easily be right - definitely not disagreeing with the premise of your argument.
