Former Real Madrid president Ramon Calderon has slammed successor Florentino Perez for selling Cristiano Ronaldo.

Calderon branded the sale to Juventus a "historic mistake".

He rapped: "I think it was a historical mistake. Cristiano asked for a raise after winning the Champions League and Florentino denied him. Cristiano also got angry because he heard that Madrid would be willing to pay a lot of money for Neymar.

"Florentino told him that if he brought a check for 100 million euros he would let him go and that's how it was."

Calderón continued: "Florentino did not accept that Cristiano was a signing of mine. I do not deny that he is being a great president for Madrid, but he does not accept well the inheritances he receives. It happened to him with (Iker) Casillas, Raúl, (Arjen) Robben and (Wesley) Sneijder."
