I think zidane is the perfect coach for a team like psg and if he join i don't think mbappe or any other player will leave the club, zidane is a great coach and everyone will surely wish to be under his supervision, psg administration must do everything to convince zidane joining the club
The problem is that Zidane's willingness to train PSG is not yet there, so that has not happened until now, even though the PSG administration can still persuade Zidane at this time to train PSG. And it would be extraordinary if PSG were able to bring a coach like Zidane into their team the following season. But I still have doubts about this because I remember the will of Zidane himself, who may not yet be there to train PSG.
