Sir Alex revealed he used to watch Ali in action by making late-night trips to various Scottish cinemas.
"I used to go in the early hours of the morning to Green's Playhouse, in Glasgow city centre, to watch Ali fight. They used to show the fights live. And when I was at Aberdeen I used to go to the Capitol during the night. It was brilliant, I loved that."
