Real Madrid president Florentino Perez says he has not spoken to Cristiano Ronaldo about his future, but will do so after the Confederations Cup, the BBC reports.
Ronaldo, 32, is said to want to leave Spain after being accused of tax fraud.
The forward, with the Portugal squad in Russia, signed a new five-year contract in November 2016, but has been linked with a return to Manchester United.
“The only thing I can say is Cristiano Ronaldo is a Real Madrid player,” said Perez, who was re-elected on Monday.
Spanish prosecutors have accused Ronaldo of defrauding the authorities of millions of euros in tax, which he has denied.
Perez said he is yet to receive an offer for Ronaldo – or striker Alvaro Morata or midfielder James Rodriguez, both of whom have also been linked with United.
“We want to keep all our players next season, including James,” said Perez.
Speaking in a further interview with Spanish newspaper Marca, he added: “Cristiano is a good guy as a professional and as a person. This is very strange and in the next few days I’ll talk to him.
“I must defend him at all costs, both as a player and as a person. What I will say is that everyone must fulfil their tax obligations. I have no doubt that Cristiano will be able to defend himself.
“What they have told me is that he has the same financial arrangements as he had in England, where he had no problems.”
