Ronaldo said: "I am feeling happy here and I am feeling calm here. But let us see what happens after the Champions League Final. I am feeling happy but in the future I don't know."

The comments were made in an interview with South American television station TV Aztec on Thursday.

Asked about his views on a move to Spain, Ronaldo said: "I have said a million times that I would like to play there, but it is one thing to dream and quite another to understand the reality.

"I don't know the club at all. But I know they like the way I play and I know that other teams in Spain like my game as well. It is good to know that they like my game, but I am happy here."

Ronaldo gave a 10-minute interview to the TV station, about half of which dealt with the thorny issue of his future.

Asked if he liked the complimentary comments attributed to the Real Madrid president Ramon Calderon, Ronaldo said: "Of course I like that. It is nice to know that other clubs are interested in you."
