Zinedine Zidane could be the right man for this Juventus but in my opinion it's a marriage that will never happen, strangely enough a coach who also managed to win 3 Champions League and many other national and international trophies finds himself without a team to coach. All this is very strange, but at Juventus I would see him well as a coach.
Zinedine Zidane has a really interesting manager career.

He managed only Real Madrid but he achieved really important achievements also. Winning the CL title 3 times in a row deserves the respect definitely! However he had a squad full of very skilled players too. Even Ronaldo was there those times. I would really like to see what he can do with a lower-tier squad.

Juventus are one of those teams I guess. It could be a really tough challenge for Juventus - especially while the Serie A isn't under Juventus domination anymore.

But truthfully I don't think he would think of going there. As far as I know he only wants to manage French national team now.
