I am surprised that there are still many people who link Zidane with PSG, however, he has said he will want to rest for an unspecified time, besides that if Zidane is willing to train PSG then Galtier will definitely be fast at PSG, in fact that doesn't happen at all , meaning that Zidane will not be a PSG coach. Galtier is the perfect coach for PSG, he just has to be able to control the egos of the star players at PSG.
I haven't seen Galtier being a perfect coach, if you say he has to be able to control the ego of each of his players, it should be quite a long time since he was appointed he should be able to improve relations between players. But until now the fact is that Paris Saint Germain is still the same as before which is still struggling with the selfishness of its players, I even think it has turned to its supporters.
