Man Utd boss Ferguson: Sunderland fans' taunts stayed with my players
Ferguson has likened the sight of Sunderland fans celebrating Manchester City's title win on the final day of last season to an experience his 'Class of 92' went through at Anfield over two decades ago.
"Any United player being involved in that game last year would have to feel it," said Ferguson.
"We have had experience like that before against Liverpool when Giggs, Scholes and Beckham were signing autographs for their fans, who immediately tore them up in front of them.
"Those things stick in your mind.
"The way we lost it definitely resonates with a lot of people in the club. The only way you can get over that kind of thing is to be better.
"There was a definite purpose about them in terms of getting the title back, particularly to take it back off City."
