Ronaldo hints at Real Madrid rift
"All the news about my renewal with Real Madrid are false," Ronaldo tweeted, without elaborating.
The Portuguese's current deal is due to expire in 2015.
Ronaldo has been linked with a move to big-spending French clubs Paris Saint-Germain and Monaco.
Even former club Manchester United have been mentioned as potential buyers, four years after he left Old Trafford.
Two weeks ago, Real president Florentino Perez denied reports that Ronaldo had rejected a new contract.
"This information is misguided," Perez told Spanish media.
"I am not going to enter into more details but I will only say that Cristiano's renewal is not deadlocked, this doesn't correspond to the reality as we stand today."
