Reports have suggested United are looking to tie Ronaldo down to a new long-term contract, while the winger continues to be admired by Real Madrid.
Ronaldo has regularly played down suggestions he will join the Spanish champions and wants to focus on securing more silverware at Old Trafford.
"What I want to do is play in the final and win the next game against West Ham and win the league," Ronaldo told Marca. "For my future, I neither know nor want to talk about it. After the Champions League final, we can talk about it."
