After victory over Granada, Ronaldo hinted at friction with Real management, which has sparked talk of the former Manchester United winger wanting out of Madrid.
Atletico Madrid icon Futre declared: "I read the newspapers and listened to radio stations in Madrid this morning and I am not surprised by what I've heard.
"They say that Cristiano wants to renew his contract, he wants to make more money. But I do not think so.
"The problem is that Ronaldo does not feel the full backing of Real Madrid."
