PSG are preparing to make their decision about Galtier already before the end of the season. This would be for their own sake as well honestly.
Because I also agree that he isn't the right coach for this team. There are much more experienced coaches with big teams out there. I would really love to see Zidane before anyone else honestly but I don't give that much chance to happen as well. Because Zidane must still have no intention to manage a club in Europe now. But if he can't take the France job then maybe he might change his mind. But I don't know if it will take PSG that much time to decide their next coach.
