Zidane success in winning three UCL trophies in a row increases his bargaining value for clubs who want to get his services. I think there is a lot of speculation regarding his future. Previously, it was reported that Zidane was reluctant to coach an EPL club, in this case Man United, because of a language barrier. I think that now the problem in question is no longer relevant. Other clubs linked with Zidane are PSG and Marseille, but these are just unofficial rumors.
I think there are many reasons why Zidane hasn't coached a club, we only know what the media reports. However, there is great hope that Zidane can return to training soon, whichever club will be his next destination will be very lucky. Madrid will part ways with Ancelotti at the end of the season, it could be that Zidane will return to coach Los Blancos.
I think the reason about the language for the EPL will still be relevant because some time before it was not only Manchester United who did approach Zidane but several other big clubs including Chelsea also tried to approach this coach but indeed Zidane's reason still seems to remain the same where he does not want to be in the EPL club to become a coach anywhere.
For PSG they tried to approach but Zidane was also not interested even though the rumors about Marseille were also very large but the clarity about the acquisition of the club by Arab investors is currently still confusing because what I can understand from the news is that Zidane is ready to be at Marseille when the resources owned are fully large because of the pouring of middle eastern investors just like PSG but it is now still a mystery because Marseille still remains in the power of its current regime.
Zidane will always be the most interesting discussion for coaches because after all with the record he has created at Madrid it is indeed a condition that is indeed worth approaching because his cold hands can bring a club to its prime only it is not easy because Zidane remains with the commitment he is currently living and is still reluctant to get out of his situation without any club.
