Speculation linking the Portuguese winger with a £100million move to Real Madrid this summer has grown in the past week.

Ronaldo, who scored his 42nd goal of an outstanding season in United's dramatic win over Chelsea in Moscow, claims he is happy at Old Trafford but he may not have ruled a move out.

The 23-year-old said: "I don't promise nothing, I don't promise nothing to my mum, I don't promise nothing to the supporters.

"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."

Ronaldo is just one year into a five-year contract at United.
