The Real Madrid star tells Europa Press agency "there are still some days to go. I am still talking about it with the club and I will see if I go."
Ronaldo was speaking at the opening of a museum in his honour on his home island of Madeira.
Ronaldo is having an outstanding year and is tipped to end Lionel Messi's four-year run of claiming the award and beat out fellow finalist Franck Ribery when the winner is announced on Jan. 13.
He says "it is only a trophy, we'll see what happens."
In October, FIFA President Sepp Blatter said he preferred Messi while making fun of Ronaldo's attitude and haircut.
