Ronaldo was reportedly considering his future in the Spanish capital after accusations of tax evasion last month.
The 32-year-old was understood to be angry at the way he was handled by the Spanish authorities and the lack of public support from Real.
But reports of an unsettled Ronaldo have quietened in recent weeks with Spanish media claiming the Portugal international has softened his stance.
However, Ramos admits he but doesn’t know what the future holds for the four-time Ballon d’Or winner.
“Ronaldo? These are personal situations and naturally I can’t add much more,” Ramos told Marca.
“The only thing, as a teammate, I can say is that I like playing with the best players and hopefully they’re with us for many more years.”
He added: “My relationship with [Ronaldo] is very good and we practically speak every two or three days, so in that sense I’m very calm.”
One player who has consistently been linked with a move away from the Bernabeu this summer is Alvaro Morata.
The Spain international started just 14 La Liga games last season after re-joining from Juventus in 2016.
And Ramos admits the 24-year-old could look elsewhere to gain regular first-team football.
“Perhaps Cris’ case is different to Morata’s, who is looking to play more and feel like a starter,” Ramos added.
“Maybe he’s looking for a way out, so we’ll see.”
