Florentino is coming under greater pressure after a difficult assembly with members.
Calderon said: "I think (the club) has an owner, called Jorge Mendes, the representative of six or seven players from Madrid, which has as president the coach, Jose Mourinho.
"Right now, Florentino Perez is a puppet. It is incomprehensible. I say this because he is a man who enjoys prestige in the business world. He's got a little empire.
"I'm surprised to see him a mere puppet operated by two Portuguese. I just do not understand it."
