Camacho, now in charge of Osasuna, says Ronaldo is "talking too much" in his first months at Real and risks mental fatigue.
Certainly, Ronaldo's interaction with the media has gone up a couple levels since his time with Manchester United and Camacho says: "He talks too much about everything about Real Madrid, for better or for worse.
"If you keep talking, you only encourage fans to target you.
"Look, when I played for Real Madrid, my mother couldn't go to away grounds because of the abuse I would receive. But when I played at the same ground for Spain, I was a hero. Playing for Madrid is unlike anyother club."
