I've never seen any of Pep's teams be more than the sum of their parts. They're always exactly as good as the players. He gets the expected performances out of them, and for literally 100% of his managerial career, he has had the best squad in the country at his disposal. I don't think he has done more than what you would take for granted. He's certainly not a bad manager, but until he actually proves that he can do more than win relatively regularly, domestically, with the best squad in the league, I'm not buying into the notion that he's one of the greatest ever. He has simply not achieved enough for that. If he'd won the CL with every club he's been at, or elevated a team like Tottenham or Atletico to the top, I'd give him the nod. Since he has simply never been tested with anything short of the best squad and the most money in the land, I'm skeptical.
