Such is the difficultly of managing a team of high profile players.
PSG is unique though. Between Neymar, Mbappe and Messi (and probably Ramos as well) the manager is barely among the 5 most powerful people in the dressing room. I dont see why a coach would want the job tbh. Tuchel and Poch seem like control freaks so PSG just provides a paycheck and maybe a couple of trophies but no chance of actually building anything.
