Former Real Madrid president Ramon Calderon believes that Madrid's determination to sign Tottenham Hotspur's Gareth Bale is due to the fact that they are afraid they will lose Cristiano Ronaldo.
Reports suggest that Los Blancos are ready to smash the record transfer sum of GBP 80 million that they paid to Manchester United for Ronaldo in 2009.
Calderon says that he knows Ronaldo is not happy with the way current president Florentino Perez has gone about his contract renewal and also believes that the Portuguese wants a bumper yearly wage.
"I know that (Ronaldo) is not happy at all with the attitude and behaviour of the president," he told TalkSport. "He is asking for 20million euros net every season, which is going to be difficult for Real to accept.
"I think the president has all his eggs on the table just in case he can’t get the renewal of Cristiano. That is my impression.
"He's afraid at some moment that Cristiano will say, 'I am not going to go on'. That will be bad news for Madrid.
"I would like to see him retire at Real but now the situation is difficult. Let's see in the next weeks or months if it can be sorted out and he can stay."
Ronaldo has been linked with a return to United, while Paris Saint-Germain have also stated their interest after the Portugal captain declared that he had not signed a new deal.
