Last season Sir Alex Ferguson announced that he would be ending his long stint as the Manchester United manager by the time he turned seventy.
That gives United's board about three years to pick a successor to Sir Alex. They will need all of that time because there has been no other manager who has been as successful as the legendary Scotsman.
While he was the assistant manager, Carlos Queiroz was definitely Sir Alex's choice to replace him, although whether the board shared this view is an altogether different issue. When he retires SAF will definitely make his views known on who will take his place, and the United board will definitely take his opinion into account.
The possible candidates can be divided into two, "Sir Alex's Lads" and "The Outsiders". Roy Keane, Steve Bruce, and maybe even Paul Ince will be looking in three years time to return to Old Trafford to replace the man who was once their boss.
On the other hand, we have the likes of Martin O'Neill and Sven-Goran Eriksson, both of whom were linked to the job at Manchester United before Sir Alex changed his mind about retirement.
Eriksson's short stint at Manchester City may have taken him out of the reckoning, but Martin O'Neill is surely in with a chance having made good progress with Aston Villa. The only question mark about him is that his ability to handle big players is not known.
Personally, I would like someone like Jurgen Klinsmann to take over and add some of that renowned German ruthlessness to United.
Who do you think would be a suitable successor to Sir Alex Ferguson?
