Ferguson, in his 27th year at the club, watched his latest collection secure a 13th Premier League title with a 3-0 victory over Aston Villa.
"We've won most of our games, drawn three, lost four," he said.
"I'm not saying they are better but great players are great players and the nostalgia thing does play tricks with your mind.
"I think Rafael will eventually be comparable to Gary Neville while Phil Jones, Rio Ferdinand, Jonny Evans and Nemanja Vidic are comparable to all the other centre-backs we have had.
"You saw this season an incredible improvement in the boy Rafa.
"He has had a fantastic season. His impetuosity has left him and he's playing with great maturity now. As the season has progressed, he has developed fantastically well.
"I think Jones might be one of the best players we have ever had, no matter where we play him.
"He has that drive about him and I think at 21 years of age he is going to be a phenomenal player. I think he can play anywhere on the pitch."
As for the United's 20th top-flight title, Sir Alex believes it tastes as good as the others, although he singles out his first championship in 1993 as a major achievement.
"It's always special when you win it. What the players had to do is focus on how they lost the league last year and make no mistakes really," he added.
"You win the title and it doesn't matter which year it feels the same, but maybe the first one is the best one as it took away all the pressure for many years.
"The focus of the team was good, they focused on the challenge of City and came up trumps."
Asked about his own future plans, he joked: "Look at me - it's taken 10 years off me today."
