Yes, substitutions that is were he fails - nevermind that he changed the game through subs dozen of times during the first part of the season (Alaves, Atletico, Getafe, Depo, Villareal etc.)..
We can basically play out of this world-football and people would still find a way to call him a fraud. No-one is psyched about the playingstyle but have a bit of respect for the coming titles - they are taken as a given now - just because we won it in december and not the last round doesn't make the league less valuable!!
