Many have long thought that the Portuguese coach would be the perfect candidate to succeed Ferguson when he does leave Old Trafford, with the two men seeming to share many similar traits, in particular a thirst for winning trophies.
When asked if Mourinho could replace him, Ferguson told ITV4: "He can manage anywhere, absolutely."
The current Real Madrid boss is no stranger to the English league having won back-to-back titles with Chelsea during a highly successful three-year spell between 2004 and 2007, having initially introduced himself to English fans when his Porto side knocked Ferguson's United out of the Champions League in 2003.
That Porto team went on to win the European Cup and speaking to an ITV programme to celebrate the 49-year-old's 10 years at the top of management, Ferguson admitted he has got what it takes to manage any club in the world.
Ferguson added: "I'm not going to put any forecasts on what is going to happen at this club. I won't last forever, but Jose can manage anywhere, there is no question about that."
Unlike Ferguson, a player of some repute during his career, Mourinho had little success on the field, making his haul of 21 trophies from 10 years in the dugout all the more impressive.
"I would never think a guy who hasn't played a game could be a top coach, but then you've got to look at his personality, I think his personality does it," Ferguson added. "He's got a marvellous, strong personality and I think that bridges that gap. That's incredible (his trophy haul). How old is he now? Fiftieth year. So he is 20 years behind me. At the same rate he is going to add another 42 trophies. At the current rate, (that is) amazing isn't it?"
Upon arriving at Chelsea Mourinho caused a media storm when he referred to himself as a 'Special One', a nickname which has stuck with him through subsequent trophy-laden spells with Inter Milan and Madrid.
"I remember his first press conference (at Chelsea) and I thought 'he's a cocky b****r, him'," Ferguson said. "He was telling the players, 'Look, I'm the Special One, we don't lose games'. Bloody hell, coming to England, he is only a young man and saying he is the Special One! But what it did, it told all the players to have the belief they were going to win the league."
