A four-time Ballon d'Or victor, the 32-year-old Ronaldo is the top European soccer player.
Last week, Cristiano Ronaldo was accused by prosecutors in Spain of defrauding Spanish authorities of $16.4 million in tax between 2011 and 2014.
It is understood that Di Maria agreed to a deal with Spain's state prosecutor on Wednesday in which the former Real Madrid forward admitted to two counts of tax fraud of nearly 1.3 million euros ($1.4 million) in exchange for a lighter sentence.
"I don't have any solution but Cristiano, like everyone else, has a contract and is a Real Madrid player", Perez told radio station "Onda Cero".
And he has also complained on multiple occasions in the past at his treatment at the hands of Real supporters, who have resorted to jeering and booing his performance on the pitch.
And Ferdinand, who played with Ronaldo at United for six seasons, hopes his former club can finalise a deal for the four-time Ballon d'Or victor. The AS report says Ronaldo "has felt comforted by Florentino's defense". Portuguese sports daily A Bola had also claimed that Perez had already been informed of the decision. "I have not talked with Cristiano", said Perez.
Impresa Italia, sconfitta la Germania. Azzurrini in semifinale
Determinante, per il passaggio del turno, la contemporanea sconfitta della Repubblica Ceca per mano della Danimarca per 4-2. Per gli Azzurrini saranno comunque valutati fino all'ultimo Caldara e Chiesa con quest'ultimo che ieri non si è allenato.
"Nobody at Real wants him to leave", Florentino said.
However, it seemed that merely standing by his star player was not the only thing on Perez's agenda during the interview and the President went on to clear the air about the player's purported move elsewhere.
Jose Mourinho's representatives have released documents to show he "was in compliance with all his tax obligations" after it emerged Spanish prosecutors have filed a complaint accusing the Portuguese coach of committing two crimes of tax fraud to the sum of 3.3 million euros (£2.9m) during his time as Real Madrid coach.
Perez, a 70-year-old construction magnate said to be close to Ronaldo, was elected unopposed on Monday for a third term in charge of Europe's most successful club.
Cristiano is the latest in a long line of soccer players in Spain among them Barcelona's Lionel Messi and Neymar to be caught up in cases over tax or transfers. Manchester United are reportedly ready to offer a bid of GBP 60 million to sign the footballer.
Ronaldo is said to have hired a law firm Baker Mackenzie to defend his 20% percent declaration to the Spanish taxman as correct or at least not a deliberate attempt, since a high proportion of his image rights earnings are from outside Spain.
