The 32-year-old signed a new contract with Real until 2021 last November and has a release clause of €1 billion.
Ronaldo is said to have told the Madrid side he wants to leave as he has had enough of the criticism he receives from some of his own club's supporters, and is also upset at being accused of tax fraud by Spanish prosecution authorities. "All this is very unusual", Perez told Onda Cero.
Real Madrid'sCristiano Ronaldo clenches his fist after scoring during the Champions League quarterfinal second leg soccer match between Real Madrid and Bayern Munich at Santiago Bernabeu stadium in Madrid, Spain, Tuesday April 18, 2017.
Those allegations were denied in a statement by Ronaldo's management company Gestifute, while Real Madrid say they have "full confidence" in a player who "will prove his total innocence in this process".
"I still haven't spoken to Cristiano Ronaldo".
"I'm sure he will speak to us about what has happened (with the tax case), which has obviously affected his credibility, and we'll see what happens". "I found out about all this from a newspaper", Perez said.
He was alleged to have defrauded the tax authority for a sum of 14.7 million Euros.
Ronaldo is now on duty for Portugal at the Confederations Cup in Russian Federation which ends on July 2. He has led Madrid to back-to-back Champions League titles and its first Spanish league in five seasons this year, and helped Portugal to win last year's European Championship.
Perez, though, has insisted that the club are "relaxed" about the situation and have no intention of letting Ronaldo go. "The only thing I know is that Cristiano is very angry with the treatment he has received in the press", he added.
