The former president of the club says that Florentino Perez depends on the Portuguese coach, who acts as if he was in control of the Santiago Bernabeu outfit
The Portuguese tactician has apologised only to the club's fans for his involvement in the fracas which broke out in the second leg of the Supercopa against Barcelona on Wednesday.
Real Madrid president Florentino Perez has stayed silent on this matter, and Calderon, who has been highly critical of Mourinho's methods, believes the acting president should set the example and have more control over the coach.
"The president of the club is Mourinho, because the true president [Perez] has not come out in a situation which required him to do so," Calderon told COM Radio.
"Florentino should come out to say that Real Madrid's history does not support this kind of acts, but he has not done that because of the dependence he has right now on Mourinho.
"The responsibility of this happening is not with the coach, who has not changed anything in the last years in the way he acts and it was logical he would not do that after arriving at Real Madrid.
"The responsibility is on who hired him and does not mend his ways nor goes out publicly to condemn a conduct which all the sport's fans reject."
Reports in Spain earlier on Tuesday claimed Mourinho was considering leaving Real Madrid allegedly due to lack of support from the club's hierarchy.
Although the Portuguese later quashed such stories, Calderon has alerted that the former Chelsea and Inter boss may quit unexpectedly.
"He has not been more than three years at a club and has not left any of them on good terms, so nothing makes one think the same thing will not happen now," he concluded.
