Former Real Madrid president Ramon Calderon was the man who brought Cristiano Ronaldo to the club after he had agreed an £ 80 million deal with Manchester United just a few months before his resignation. He has seen his successor Florentino Perez dominate the headlines with the world record signing of Gareth Bale.

Calderon says that he is confident that Ronaldo will leave Real Madrid in the next few years to return to United, which still remains a special club for him. Even though he came through the ranks at Sporting Lisbon, Ronaldo became one of the best at United.

The possibility of a return to Old Trafford was mooted in the summer, but it is believed that the retirement of Sir Alex Ferguson made Ronaldo consider his future. He made an amazing U-turn and signed a five-year contract with Real Madrid, which also made him the best paid player in the world by a long distance. It is believed that his current contract earns him more than £ 20 million per year. Ronaldo has been sensational since the move in 2009. He has already scored 41 goals this campaign and he is the reigning holder of the FIFA Ballon d’Or award.

He managed to beat Lionel Messi after scoring more than 60 goals last season.

"You never know. I know when I signed him, he was saying that Manchester for him has been like his house, he was quite happy there with the fans, with the club. At the time with (Alex) Ferguson, he considered him like a father, and everything for him in Manchester was perfect. But he wanted to come to Madrid and play for Real, and you never know, maybe at the end of his career he would like to come back to England and back to Manchester,” said Calderon.
