The former Real striker told AS: "Everything Florentino does is successful. He's a genius."
Perez has spoken of Ronaldo returning to the club in an off-field capacity, but the Brazilian isn't planning to retire anytime soon.
"We'll see ... I am not planning to return to Real Madrid just yet. I have very good relationship with the club, and more specifically with Florentino. But I'm a player, so I am still not ready to work for Real Madrid."
