I heard rumours that Zidane personally does not want to coach any team in France. And so Zidane is not interested in coaching a rich club like PSG. Taking charge of a team like PSG is very difficult. Also in the previous days we have seen PSG's coach management and players impressed. A coach cannot make independent decisions or arrange the squad. Zidane will not be interested in acting subserviently. This could also be a reason for PSG's rejection of Zidane's offer. But if PSG got an experienced coach like Zidane, maybe the team would have been able to play better in the Champions League.
It was the right decision made by Zidane not to become a PSG coach and he should have rejected the offers because PSG is a team that is too wishy-washy and often makes things more complicated if it doesn't go according to what they want. It is proven that by changing coaches, PSG is now increasingly unclear what will be its goals and on the other hand, losing several stars will certainly be additional work for PSG if they fail to win the Champions League title again.
There is no other choice but to clean up what they think is wrong and from the start of their next coach I think PSG must provide a wide space to be able to build a squad with a winning mentality.
