I'm gonna be honest here, I'm not following closely PSG just watched CL games and a couple of games in French league. I'm not super familiar with Poch either. I believe the main issue of PSG is not really the coaching, Truchel is obviously a great coach but has not been able to handle it. Too many egos, a structure that needs to become more professional, PSG is rather young with no winning culture, a lot of politics inside the locker room. Changing the coach every other year is not helping to create a stability. Maybe Zidane would be able to put the egos in check and get the offensive players to do the efforts when the team does not have the ball but I am not even sure.
