With players that have been there, done that, many are 28+ and will not change their ways in a few months? Fucking stupid. Benitez level adaptability. Dude is a fucking moron for thinking they would be as open to teaching as Pep's taboon of under 23s.

ATM he's a preacher drillmaster that acts like he knows better and that's that. If he stays this way, the only clubs this will work with is sheikh teams with deep pockets who will buy him the material he needs.
Even Barcelona this would be difficult, because he'd need to make concessions for lazy ass 30+ forwards who have won it all and wouldn't be nearly as reliable defensively as this way of football demands them to be.
