By my reckoning the really great managers - even the good managers - make an immediate impact and the weakness in the system gets exposed pretty quickly. Pep at City, Klopp at Liverpool etc. You can see the model straight away. I don't see anything with this new fella at United. I appreciate he might not have all the players to play the system but if he doesn't have any of the players to play the system then he's fucked. Pep needed a new goalkeeper and fullbacks/wingbacks, everyone could see it. What does this fella need? A new 21 player squad?
