Zidane is not coming to manage Man Utd for sure because the situation of man utd is not good and a lot of politics is going on in Man Utd. And man utd is just not making the right decisions for a long time. So i don't think Zidane is actually going to associate himself with a club like that, to be honest. I believe Man Utd should be looking for other options because I don't think money is going to be enough to bring Zidane as the coach of the team. Zidane is probably the right person but Zidane will not want the job as far as I think.
Zidane won't come to Man United because of other reasons. It is not about the condition of the club which is not good or unstable. However, the politics or drama on Man United, can be one of the reasons. Zidane is a typical coach who wants to develop a team with his own style. He doesn't want to be intervened by the team management. If Man United management always have the intention to intervene anything to the coach, Zidane probably won't be interested. For now, I think Man United is better to keep Ten Hag as the coach. Just evaluate until the season is over.
I don't know the reason behind the many reports in the media about a proposed deal that'll see Zinedine Zidane replace current Manchester United manager Erik Ten Hag when the Dutchman leaves the club or whenever he's been sacked but one thing I know for sure is that a manager of Zinedine Zidane's character will not like to manage a Manchester United side that's having some issues concerning the management of the club.
The Glazers tends to have too much direct influence on the Manchester United team and Zidane would want a team which he makes all the vital decisions which Manchester United doesn't fall under that category.
I have read this a dozen of times now that Zidane refuses to manage a team from the Premier League. I don't know if this is a rumor or not and what his reasons would really be to refuse it, but if it is true then this is of course unlikely. It also doesn't make much sense because Zidane has won so many important titles already and he prefers to have teams that are ready to win titles and not need half a decade to be trained in order to then be ready to win titles. Manchester United can't win big titles in the next few years. They need to be newly composed as a team first and I don't think Zidane would want to do that.
