Zidane the best solution for PSG. Apart from Zidane, there are other coaches who have a winning mentality, such as Rafael Benitez and Jose Mourinho. Both Rafa Benitez and Mourinho have proven capable of presenting several prestigious European trophies to the clubs they have worked with.
Zidane will not be willing to coach PSG at this time. There is one opinion that says because PSG still has Lionel Messi, Zidane avoids him. On the one hand, this assumption is true and makes sense, although professionalism is more important.
Everyone talks about how Zidane could be a better deal than Pochettino, but we are forgetting that Zidane managed a team that was amazingly well fitted for UCL, and not even just La Liga, or any other league, or any other cup, it was a great team for UCL and it is even still valid today after certain players left.
This is why I am not 100% confident that if Zidane comes, he could easily win UCL, he could still have trouble as well just like Pochettino did. This time around, Zidane could have a better chance because there is no doubt about Mbappe, so PSG could focus on other positions with ease, and may take a year or two for them to get other superstar level players in those positions, but having Mbappe locked means a lot for them for sure.
