Real Madrid president Florentino Perez says he has not spoken to Cristiano Ronaldo about his future, but will do so after the Confederations Cup.
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.
“Obviously something has happened, something has affected him, his credibility,” Perez told Spanish radio station Onda Cero. “I’m sure he will tell us and we will see.
“It’s no coincidence that he’s in a very important tournament, the Confederations Cup. It hasn’t finished yet and I don’t want to disturb the Portuguese team.
“He just wants to be the best player in the world. If Cristiano wants to leave Real Madrid, it won’t be for money.”
