Real Madrid have revealed that they are waiting for confirmation from Cristiano Ronaldo that he wants to join the club, before entering talks with the player.
The 23-year-old Ronaldo has said he hopes to “complete his dream” of moving to the Bernabeu, despite Manchester United insisting he is “not for sale”.
But Real president Ramon Calderon said: “Once Ronaldo announces his future and once his club accept to sell him then we would have talks.
“Right now he’s a United player – we’ll not interfere or create any problems.”
Ronaldo has indicated he will make a public statement about his plans over the next few days.
After Portugal’s exit from Euro 2008, Ronaldo revealed his desire to “take advantage of a great opportunity” with the Spanish champions.
“Everybody knows what I want but things don’t only depend on me,” he said. “I am not the person who decides but I hope to complete my dream.”
Ronaldo has insisted he is not concerned about upsetting United manager Sir Alex Ferguson.
“It is my opinion,” added Ronaldo. “That is why I don’t mind if people get upset. It is my decision. It is what I want.”
Real coach Bernd Schuster has urged Calderon to “pay what is necessary” to bring him to the Bernabeu.
“What is most important is to win the Champions League and he can help us achieve that,” said Schuster.
