Fergie was manager for United while Hughes played for the club.
Hughes has gone on to an impressive career in management at the Wales, Blackburn Rovers and now Manchester City.
He told Inside United: “It’s difficult to assess that because you don’t know what ambitions the players have.
“Currently we’ve got (Ryan) Giggs, (Paul) Scholes and (Gary) Neville taking their coaching badges. That’s great and I encourage them to do that because it gives them a platform if they want to stay in the game.
“It can be difficult to pinpoint who would make it as a manager.
“For instance, nobody here thought Mark Hughes would become a manager, never in a million years, and we all thought Bryan Robson was a certainty to be a top manager.”
