The legendary Scotsman ruled the roost at Old Trafford for 27 years between 1986 and 2013, with Welsh winger Giggs being his most successful and most selected player during that period.
The pair have won 13 Premier League titles side by side, but Giggs says he was not one of Ferguson’s four favorites away from criticism.
“There were three or four players he never participated in,” said Giggs at the beIN SPORTS club of champions.
” [Eric] Cantona was one – Bryan Robson, Roy Keane and Cristiano Ronaldo. They were all winners in their own way.
“They did things on the ground, so he never felt [like he had to]. ”
Giggs added that Ferguson’s treatment of Cantona would often surprise his teammates.
“Eric, there have been games where Eric has done nothing,” he said.
“He didn’t score, he didn’t run like a Tevez or Wayne Rooney, he had no impact. But he knew that sooner or later he would be fine.
“We would be sitting in the locker room thinking” that he should run against him, he must have pop on him because he did nothing today. ”
“But next week, he would mark the winner or produce a moment of magic, so he handled the big names very well as long as they did it on the pitch, he treated them differently.
“He was a master of psychology, he was a master at getting the most out of some people like putting an arm around him, or giving them a rocket at half time or at the end of the game or the leave aside knowing that the player would respond positively. ”

Giggs says he has been the subject of Ferguson’s anger many times, but that he was not afraid to bite.
“I have often fallen with him,” he added.
“I mean the number of times I would say in my career, six or seven times it was a few weeks’ salary, I was fined for answering, for having an argument.
“When it is not very beautiful, you are in the locker room, you have just been beaten or you had a bad performance. And I couldn’t help but go back.
“In fact, later in his career, he told me he liked it, it meant you care about him. He would still fine you for two weeks because he wanted to show that he was in charge, but he liked him, as long as he didn’t cross the line of course. ”
