Manchester United winger Cristiano Ronaldo is keen on a move to Real Madrid.

Sources close to Ronaldo's camp have told AS that the Portugal international is flattered by the interest of Real and would jump at the chance of moving to the Santiago Bernabeu over the summer.

"It's clear that he would like to play for Real Madrid," said the source. "Who wouldn't? His present situation at Manchester United is complicated and the boy is not calm in that sense."

Ronaldo's representatives are pressing United for a new, improved contract, but American billionaire Malcolm Glazer's takeover has forced talks on-hold.

The youngster has also been criticised by teammates this past season, further fueling reports that he is unsettled.

The source was also asked if Ronaldo would be interested in joining Barcelona, but was insistent that only Real Madrid would tempt him from United so early in his career.
