Wow, I understand refusing PSG (Zidane had reasons to do so), but refusing a Brazilian team that is at the bottom (in terms of results), which means a “rise” is almost guaranteed, is very strange. But in fact, Zidane can afford it - he does not need money or titles, so he can be unemployed for a long time and wait for an option that interests him.
He won't in rush taking any job ... he could go anywhere with his track record.
Zidane is indeed a figure that is not easy to predict. Even though there were many offers to become a coach he did not accept them, even the last one was the United States which tried to offer him a high price but Zidane still did not accept it.
Some reports suggest that the reason Zidane rejected many offers is that he is still waiting for an offer to coach the French national team. Still, it seems that Zidane will not have a chance because the French Football Federation (FFF) has extended Didier Seschamps' contract until 2026. France is still satisfied with Didier's leadership as national team coach. France after yesterday at the FIFA Worldcup Qatar 2022, France was able to become the second champion after the match against Argentina.
