Real Madrid have confirmed their interest in signing Manchester United winger Cristiano Ronaldo if the Portuguese star becomes available.
Ronaldo joined Man Utd from Sporting Lisbon in August 2003
Ronaldo is in talks about renewing his contract, which runs until 2010, and says he wants to stay for "many years".
Real president Ramon Calderon told a Spanish TV station: "We really like him but he belongs to Manchester United and they have to decide to sell him first.
"If that is the case then we'll be first in the queue."
Calderon, who also hopes to prise Brazilian midfielder Kaka away from AC Milan, insisted Real would not pay a £54m (80m euros) price tag reputedly placed on Ronaldo.
"I don't think any player, even someone with Cristiano Ronaldo's quality, is worth that money, but we are definitely interested if Manchester United want to sell him," he reiterated.
I have a good contract, in financial terms, but what really matters to me is to show my best form
"I would love to see both Kaka and Cristiano Ronaldo play for Real Madrid next season, but it won't be easy. Any big club would have this sort of objective and Real Madrid is a big club."
Ronaldo, 22, has been in superlative form for United this season, scoring 18 goals including 16 in the Premiership.
"It is a good sign to know I have so many clubs interested in me, such as Real Madrid," he said. "It means that I am valued.
"But I am very happy where I am and I hope to stay at Manchester United for many years."
United want the player to sign a new deal, which will take him up to 2012.
"I have a good contract, in financial terms, but what really matters to me is to show my best form," he added.
Ronaldo is currently away on international duty with the Portuguese squad.
He scored twice as they beat Belgium 4-0 on Saturday, but is a doubt for Wednesday's qualifier against Serbia in Belgrade after picking up a heel injury in training.
Ronaldo collided with an opponent during a practice match and left the field with an ice pack around his left foot.
"At this time we don't know if he will play," said Portugal team spokesman Onofre Costa. "He sprained his heel - it doesn't look very serious but we are not sure if he will be fit."
