The cult that follows him really does him no favours.
Is he a coach for a really big team? Probably not. Is he the worst coach on earth? No. But those are the two options you must choose from it seems.
If you compare him with Pirlo, you can immediately tell which one has years of experience. Our organization is a complete joke. Never in my life did I think I would see our sweeper marking the #9 in our own half when the rest of the team is in the opponent's half.
With the improvements we made in our squad, would we be better right now with Sarri? Probably yes. Would we be better long-term, if you anticipate growth from Pirlo? I would probably still have faith in Pirlo because his attacking ideas are far superior.
