Sneaky asshole? It's perfectly possible that he's butthurt about something without being a sneaky asshole. I'm thinking about the rumours that he wanted to get rid of some big names like Pique. There are 5 million or more ways to praise your players without making a Barca reference. "I have seen" instead of "I have trained" would be one. If someone like Ancelotti said something like that - different story. He has coached multiple squads for decades and isn't strongly associated with a few certain players that he has coached. When Guardiola says that most people will clearly understand it as "Lahm is a more intelligent player than Busquets, Xavi, Iniesta, Messi" as those are the few important players he has "ever coached". What else?
Not that I'm strongly concerned. It was just a neutral question if he might be butthurt about something.
