Ferguson accused Pogba of not showing the club "any respect at all" after keeping them in the dark about his negotiations with Juve.
But the 19-year-old has defended his actions by explaining that his chance at Old Trafford never arrived.
"I don't know why he said that," Pogba told L'Equipe. "A 19-year-old player who said no to Ferguson - maybe he took it badly?
"There are things about which we failed to agree.
"I don't regret anything. I learnt a lot there. But you have to be part of it to understand my decision. It is a feeling I had with the coach.
"The coach trusted me, but he didn't play me, saying I was too young. He said 'Your time will come' but it didn't come.
"Despite his 25-year career, despite the fact he was the boss, my objective was to play. I am impatient.
"Now I want to become a regular starter and become one of the best players in the world.
"To achieve that, there is only hard work - I learnt that alongside the great players at Manchester United."
