Ronaldo, 23, has been heavily linked with Real Madrid and has said it would be a "dream" to join the Spanish side.

Blatter insists that players should be free to play where they choose.

And Ronaldo told Portuguese broadcaster TVI: "You know what I said, what I want and what I would like. I agree completely with the president of Fifa."

The Portugal winger, who is recovering after undergoing ankle surgery last week, added: "Now I have to wait and see but I do not know where I will begin the season."

Blatter irked United with his claims on Thursday comparing transfer trends to "modern slavery".

A United spokesman said: "All our players enter into their contracts after an open and free negotiation."

And the statement continued: "Most of whom do after taking advice from a Fifa-registered agent.

"Many do so on a number of occasions and enjoy long and successful stays at Old Trafford."
