The Manchester United manager Sir Alex Ferguson is uncertain whether Roy Keane will return to football management.
Keane resigned as Sunderland manager yesterday after 27 months in charge of the Black Cats and his future in the game remains unclear.
Ferguson says it's difficult to say whether he will be back... he's an incredibly controversial character, every week he always had something to say about the game.... he was the same as a player.
Ferguson, who Keane played under at Manchester United, added he's such an interesting character and did a decent job up there.
Former team-mate and now Manchester City boss Mark Hughes believes Keane's exit may have come as a result of not taking a decent break between finishing his playing career and taking over as manager at a club.
The 37-year-old Irishman went to Sunderland in August 2006 almost immediately after injury finished his playing career at Celtic in June of the same year.
