Real are understood to be currently in negotiations to sign Kaka, while they have long been linked with a move for the Portugal international.
'Kaka, Cristiano Ronaldo and Lionel Messi are the best players in the world," Perez told Atena 3. "I'm going to work to bring Kaka and Cristiano Ronaldo to Real Madrid.
"I've been here a few days and neither (former president, Vicente) Boluda nor anyone else has talked to me about this supposed agreement. What would be very good is to see these great players at Real Madrid this season. Cristiano would be one of these."
Perez is close to making his first signing since returning as president with Madrid on the verge of completing a world-record transfer deal for AC Milan playmaker Kaka.
Chelsea denied last night that they had made a £73.3 million offer to Milan, something which delights Perez, who added: "This statement is an advantage. If Chelsea are not competing with us it is good news.
"The problem wouldn't be the presentation of Kaka, the problem would be if we are capable of fixing it so he plays for Real Madrid.
"We have good relations with Milan. I'm a friend of (general manager, Adriano) Galliani which will make this agreement easier. Moreover, the player has shown his desire to play for us."
