Perez is favourite to return as Real Madrid president this summer.
Reports have suggested that Ronaldo is no longer Real’s No 1 target but Perez admits they are still interested.
Perez told Marca: “He’s also a player that would be very good if he came to Real Madrid. What I know is what I’ve read, that there is an agreement by means of which he would come for £80 million…”
Perez added on the transfer fee: “Next week we will look at the numbers and nobody should doubt that we are going to design with our sporting advisors a spectacular project.”
