#2 Zidane effect
Zinedine Zidane is an epitome of world-class players who transitioned well into management. In two short years, he achieved more success at Real Madrid than the team did in over six years of the Galactico era (2000-2006).
One of his greatest qualities as a manager has been his excellent man management. It has been seen in the way he interacted with his players and rarely criticized any publicly.
His philosophy revolved around attacking play and that is something that United desperately need. It has been widely reported that he is in line to take over if Mourinho faces the chop.
Also, it has reported that he has outlined a five-man wish list of players he would want to be signed. The United leadership may want to bring him on board at the earliest opportunity because someone of Zidane's pedigree may not be out of work for long.
