Ronaldo's future at the Bernabeu has been the subject of constant speculation this summer, with the 28-year-old recently admitting he missed English football.
Manchester United have been linked with making a sensational move to bring the Portuguese ace back to Old Trafford after selling him to Real in 2009.
However, Ronaldo insists he has no plans to leave Real and is happy to continue playing in Spain.
"I enjoy of course to play there [Real Madrid], I play there for four years so I want to continue there," Ronaldo told Sky Sports News.
"It is not the best day to speak about my future. I am going to have time to speak about that at the beginning of pre-season."
Real have previously attempted to curb the rumours about Ronaldo's future by announcing on several occasions that they intend to agree a new contract - with the player having two years left to run on his current contract.
And new coach Carlo Ancelotti recently made it clear that Ronaldo is central to his plans at the Santiago Bernabeu.
The Italian boss said: "My opinion is easy. Ronaldo's a fantastic, marvellous player.
"It's an honour to coach a player like Ronaldo like it was to coach Zidane.
"Ronaldo was not on the list of players like Brazilian Ronaldo, Zidane and Ronaldinho that I coached.
"He will be on the list of players I coached now and I am so happy for that."
Real president Florentino Perez outlined his confidence last month that Ronaldo will sign a new contract.
He told 20minutos: "He's our most important asset, and we will build the future of Madrid around him.
"Soon we will clarify this issue. I have no doubt that Cristiano is going to retire at Real Madrid. I'm convinced that he'll renew. The renewals are done before the season starts."
