Former Real Madrid president Ramon Calderon has launched another furious attack on Florentino Perez. Amid the latest round of controversy surrounding Real coach Jose Mourinho, Calderon insists president Perez is the man ultimately responsible for the club's current crisis.

"The victory is his (Mourinho's)," barked Calderon, "because the president brought him knowing his personality, Mourinho has not fooled anyone, and behaved as well as he's behaved with his previous teams."

Calderon says Perez has sacrificed the club's image by giving all footballing control to Mourinho.

"He's a puppet who does not control anything or has an interest in demonstrating that he is the president," added Calderon on La Xarxa.
