Ronaldo was named the FIFPro player of the year on Monday, after scoring 42 goals and helping United to win the Premier League and Champions League titles last season.
“I still think he will beat 25,” said Ferguson. “It is going to be difficult because he has had a stop-start beginning to the season.
“He had the operation on his ankle so he has missed a few games and he is just getting his rhythm back.
“The number of goals he scored last year was absolutely phenomenal. You cannot describe it any other way.
“But I hope he can be equally as good this year in terms of his contribution to the team.”
