Real Madrid president Ramon Calderon insists the prospect of prising Cristiano Ronaldo from Manchester United is "not impossible".

Calderon said: "There are many fans who would like to see Cristiano Ronaldo playing in the Bernabeu. It is very difficult because he has a contract with a club that does not want to sell him. It is almost impossible, but absolutely not impossible because it can happen that from now until the market is closed something could change."
