The former Manchester United ace has excelled in Spain having plundered a whopping 87 goals from 89 games in two years.
Weekend reports hinted City would offer Ronaldo an astronomic wage to move to Eastlands, although the Portugal international insists that money is not everything.
The 26-year-old accepts he would perhaps earn more money away from the Santiago Bernabeu, however, he is happy at the club and wants to stay.
Ronaldo still has four years left on his Madrid contract, but would sign a contract for life if possible.
"I am not thinking about leaving Real Madrid," he told Marca. "I'm very happy here. I'm great.
"I could perhaps double what I have in my bank account elsewhere, but for me happiness is the most important thing.
"If I could say to the president today I'd sign for ten years then I would. Why not sign for life?
"I am not going to City. I give you my word. I want to fulfil my contract."
