The Portugal international forward also claims that he does not play for the Spanish champions just for money.
"I play for the passion I have for football and for the love of the teams I represent," he told France Football. "If I played for money, I would be at another club.
"All players love it when teams like Paris Saint-Germain, Manchester United or Chelsea are linked to them. Moving is not something I am thinking about though. I am happy at Real Madrid and I want to stay here and win things.
"What happens in the future is in the lap of the Gods. In life anything is possible and nothing is impossible, but for now I am not thinking about another club or a new contract."
Ronaldo joined Madrid from United in 2009.
