Former Real Madrid president Ramon Calderon believes that there could be a chance of Cristiano Ronaldo returning to Manchester United in the future.
The Portugal captain moved to Old Trafford when he was 18 years old and went on to become one of the world's best players before moving to the Bernabeu in 2009.
"You never know, maybe at the end of his career he would like to go back to England and Manchester United, but I would love to see him end his career with Real Madrid," Calderon told talkSPORT.
Ronaldo's £80m price tag made him the most expensive player in history until Gareth Bale joined Madrid from Tottenham Hotspur for a reported £85m last summer.
