If Zidane wants to, he can head PSG and coach them. I'm sure PSG would like to see a coach like Zidane in the team. Although the rumors with Zidane increase from time to time, they are usually not true. It is not surprising that such a rumor comes out for PSG again. Of course, Zidane can be one of the best options if they want to win the European cup, as well as the goal of winning the French league 1.
I doubt that PSG will be a good option for Zidane. Zidane had a lot of backing and support from Madrid and Madrid is a different team from PSG. Madrid had everything they needed when Zidane was there. Winning the Champions league is not the same as making the team strong. Madrid was already strong but PSG is not the same. They are very inconsistent and they need a structure.
Zidane can't do that to be honest. What PSG needs is a coach that has a system and can build players. Luis Enrique can do that.
If Enrique gets the backing and support required at PSG he can turn them into a fearful force.
At the moment the psg team is more divided than ever. Because the players who were in the PSG club in the previous season, but PSG will not get those players this season. If the required players are not available then the coach will struggle to organize the team.
The 2022/23 season was a season full of players for PSG. Since PSG had good quality players in 2022/23 season then PSG should have appointed good players as well as an experienced coach in their team. In that case they could have chosen Zinedine Zidane or Luis Enrique.
Now, if a good quality coach is appointed then new players have to be appointed again otherwise it is never possible for a coach to make the team into a strong team.
