Ferguson has spent 24 glory-laden years at Old Trafford but is coming to the end of his tenure, and Sneijder says that Real Madrid's new boss wants to take charge of the Red Devils when Ferguson does decide to call it a day.
''I have had many deep and long conversations with Jose and I would put money on him taking over from Ferguson,'' Sneijder told the Daily Star Sunday. ''I know the job he would want is to be Manchester United manager.
"To be honest, he is probably the only coach in the world who is capable of taking over from Alex Ferguson. When Ferguson retires, in my mind, it's a deal already done in people's heads. One world-class manager leaves and another one takes over.
"I know Alex Ferguson will have a big say in who takes over from him - and, even though they have their differences, there is a big mutual respect."
Mourinho has said in the past that he is keen to return to England and the Dutch midfielder confirmed his desire to manage in the Premier League is still strong.
"I know how excited he is to get back to the Premier League. When he talked about it, he was like a little kid. He was so excited. It really turns him on," he added.
