#1 Zinedine Zidane
There could have been fifty other names instead of the Ryan Giggs and Antonio Conte, but it all ultimately zeroes down to this man - Zinedine Zidane. The United fan base has split into two halves - one group has faith in Mourinho while the other group wants him out.
Almost every member of the latter group will suggest only one man as the manager of their beloved club, that is Zinedine Zidane.
The Frenchman's managerial career is not a long one, but what he has achieved in these very few years for Real Madrid is exceptional. Besides winning six other trophies, Zidane made a hat-trick of UEFA Champions League wins, making the greatest club footballing event their patented trophy.
If Mourinho's future is already sealed and that's not in Old Trafford, Zidane might be the answer for United.
