#1 Zinedine Zidane
Zidane was one of the best footballers of his generation, and he has won all the major trophies in the world of football as a player and manager. His mental strength and dedication is what makes him incomparable.
His managerial stats with Real Madrid are quite astonishing. He led Los Blancos to 3 consecutive Champions League titles, putting his name in the history books.
The Frenchman left the club last year, 5 days after his Champions League triumph. He could also work his magic with fellow Frenchman, Paul Pogba, who was not in Jose's good books. Zidane might also bring back Lukaku and Sanchez in their best form.
Zizou has been linked with Manchester United for quite some time now, and I feel he will be the best replacement for Jose Mourinho.
His fierce attacking mentality and lightning fast counter-attacking tactics might prove to be beneficial for the Red Devils.
