United endured a disappointing 10 months under Moyes – the club eventually sacking the former Everton boss in 2014 when his team crashed out of the Champions League.
And Sir Alex, speaking in a new BBC documentary ‘Sir Alex Ferguson: Secrets of Success’, revealed Mourinho wasn’t the only man Old Trafford officials were keen on appointing.
“When I announced my retirement, do you honestly believe that one man could decide the future of Manchester United?”
“That’s absolute nonsense. There was a good process… Jose was going back to Chelsea, Carlo Ancelotti was going to Real Madrid, Jurgen Klopp had signed a contract with (Borussia) Dortmund, Louis van Gaal was staying with Holland for the World Cup.
“I don’t think we made a mistake at all… we picked the right man. Unfortunately it didn’t work for David.”
Van Gaal eventually took over at United after the 2014 World Cup, with caretaker manager Ryan Giggs becoming his assistant.
On Giggs’ credibility as a possible future boss at Old Trafford, Sir Alex said: “If (he) had retired six, seven years ago… at, say, 35, quite likely I would have made him my assistant and quite likely he could have moved straight into the job with the experience of being an assistant manager to me as he is doing with Louis van Gaal at the moment.”
