Calderon believes Ronaldo will want to end his career at Old Trafford.
He said in The Sun: "I do not think he will finish his career at Real.
"I feel that one day he will return to England. In Madrid, he is pleased with the city and the fans. But I think his relationship with Florentino Perez is not as good as it was with Alex Ferguson at Manchester United.
"Ronaldo loves father figures. With Florentino, he does not have that rapport.
"The relationship is bad or actually non-existent. He stays at Real despite the chairman."
