Ronaldo has courted interest from mega spending Manchester City.
But the former Manchester United winger said: "I do not look outside of Real Madrid. Here I am very happy, I'm great. If I left, I could double the money I have in my account, but to me it is more important how you are treated.
"If today, the president asked me to sign for ten years, I would.
"I do not know what could happen tomorrow."
