In the wake of Manchester United's historic victory over Chelsea last night, Cristiano Ronaldo remains non-committal over his future at Old Trafford.

The Portugal international played a key role as United lifted the European Cup for the third time, scoring his 42nd goal of the season to give his team a 26th minute lead, only to see his penalty saved in the shoot-out that followed.

Amid growing speculation, Ronaldo has consistently been linked with a move to Real Madrid, with the player at one stage declaring that he would make a decision on his future after the final. And despite last night’s triumph, the player, while insisting he is happy at Old Trafford, is refusing to rule anything out.

"I don't promise nothing, I don't promise nothing to my mum, I don't promise nothing to the supporters," he said. "I want to stay, but the future... no-one knows. I want to stay. We are going to see in the next two weeks, I don't say I make a decision."

Ramon Calderon, the Real Madrid president, believes the club's hopes of prizing the player away from Manchester depend entirely on Ronaldo.

"The players play where they want. If a player decides to leave he is unstoppable, slavery was abolished a long time ago, nobody can prevent a player from moving," Calderon said.

"If the player is firm in his decision there is no one who can hold him back. I have always said that if Manchester want to sell him, we will ask about him, and if he wants to come and we can pay what they ask."

However, Carlos Queiroz, United's assistant manager, insists Ronaldo has no intention of leaving. "Without doubt he is going to continue in Manchester. He is very happy with us, he has a contract and there is no fear that he will leave," he said.
