The Brazilian continues to struggle for regular first-team football at Real and he was linked with a return to former club AC Milan over the summer.
With the transfer window on the horizon, speculation has claimed that Corinthians will try to tempt the 30-year-old back to Brazil and MLS club New York are also weighing up an offer.
However, Bosco Leite says there have been no negotiations regarding a transfer and confirmed that Kaka's preference is to stay in Europe.
"I don't know about that," Leite told Lancenet with regard to the rumours. "For now, as it stands now, he wants to stay in Europe.
"That might change but today, I don't know.
"Corinthians were never mentioned. And Corinthians themselves never said anything either."
