Five NFL head coaches who could manage Manchester United

1. Bill Belichick, New England Patriots

Long considered the Ferguson of the NFL, Belichick does nothing but win, getting the best out of all his players and tactically beating his opposing coaches long before the game has kicked off.

Three championship in the last 12 years may not seem a lot, but in the salary cap era of the NFL, it is damn impressive. The only man in America who could successfully take over the job.
