Ronaldo relinquished the crown he won in 2008 to Barcelona star
"I'm going to win the Ballon d'Or back, this year or next," he declared as quoted by Marca.
"I have an ambition to become the best player in history."
The 24-year-old also declared that his troublesome ankle, which kept him out of action for two months, is in good shape and will not require surgery.
"The ankle is fine and if not the Real Madrid doctors will see it right. I am sure I will not need an operation," he noted.
