Cristiano Ronaldo's agent Jorge Mendes has dashed any hope of Manchester United re-signing the prolific player by insisting that he will retire at Real Madrid.
Recent reports have suggested that the Portugal captain wants to return to Old Trafford because he has become disillusioned with life in Spain.
However, Mendes has insisted that it would be "impossible" for any club to lure the 29-year-old away from the Bernabeu.
"Cristiano Ronaldo will retire at Real Madrid when he turns 40," Mendes told Cadena Cope. "He is very happy at Madrid.
"It is impossible to lure Ronaldo away from Madrid. He breaks all the records and is regarded as the best athlete ever. He is happy at Real Madrid and has always been happy here. He will break all the records and then retire at Madrid.
"Manchester United will always have a place in his heart because he spent six years there, but he is only thinking about Madrid now and will always stay here. He is delighted to be at Madrid. People know that it is impossible to sign him, so it's not even worth calling."
Ronaldo spent six years at United before signing for Madrid in 2009.
