The great Manchester United manager was in charge of Rougvie at Pittodrie back in the 1970s which allows the now-57-year old to give us some insight as to how 'Fergie' used to operate.
Rougvie was opting between football and becoming an electrical engineer when Ferguson forced him to make a decision.
"I still respect him and will speak to him, but if you asked anyone who played for him and they will tell you, he's a b******," Rougvie said of Ferguson.
"You can't argue with his success. But it was all about him. When I was a youngster at the club he cancelled my day release to go and study to be an engineer.
"All he cared about was the team. He probably cut my future livelihood in half.
"It took me a good few years to get back and build up a career after I hung up my boots.
"I'm not bitter. He didn't give me any money, but he gave me a bagful of medals."
"He called me a mercenary and told me to f**k off, so I f**ked off," he added.
