While awaiting details of the financial arrangements to be finalised, Ferguson stressed that money had no factor in the decision, the boss spoke to reporters being officially unveiled at Old Trafford.
“Manchester United are the only club in the world I would have left Aberdeen to join,” he said.
“I’m looking forward to a tremendous challenge. Everything has happened so fast that I’m slightly bewildered.Â
“I recall the late Jock Stein once telling me that the biggest mistake he made was to turn down the Manchester United job.
“And I made sure that I wouldn’t do the same, but it will be a great wrench to leave Aberdeen.
“After eight years of working with everyone at Pittodrie, I can’t begin to express the sadness I feel. It has been an unforgettable experience.”
