To be sure, Zidane is the most appropriate choice for PSG as a replacement for Pochettino next season. I have no doubts about Zidane's coaching capacity and ability, he is the best manager ever with a good collection of titles. Zidane won a lot at Real Madrid but of course we can't fully expect that he is capable of doing that with PSG as well. But at least PSG have chosen the right manager to handle their luxury squad next season if Zidane really manages to sign that contract.
Zidane hesitates to join PSG because he looks like to aim at the France national coach position. He would like to wait for that position because he sees something: France currently has a very good generation with Mbappe is a biggest star but they have more than that; Deschamps already won title with France and probably he will leave that position after the World Cup. Zidane knows that if he wastes this opportunity, he will have to wait for 4 to 6 more years and it means too long. That will be the end of this gold generation and if he becomes a coach of France next 6 years, maybe he will have a squad that does not have enough competitiveness to win titles.
With PSG, lot of chance for Zidane to join them. Each year, he can get a new invitation from PSG.
in the near future PSG will immediately sack Pochettino and technical director Leonardo then the chair of PSG training head will automatically be filled with a new coach next season and the latest picture says PSG will appoint Zinedine Zidane as main coach next season, if Zidane is officially appointed as coach then it is a tough task will be carried by the PSG coach because the club is very ambitious to win the UCL title.especially since they have successfully kept the young star Mbappe at the club, although Zidane has proven his quality as a player and as a coach, Zidane is not easy to suppress the ego of PSG star players
I believe that time for Pochettino in PSG is ending and he is counting down his last days in PSG. If not Zidane, PSG will still try to find another coach. The best scenario for Pochettino is PSG will allow him to be their coach till the end of this season. And he will have to go.
Lot of rumor that PSG want to sack him and Mbappe does not want to work under his management. Lot of negative things are against Pochettino.
