Speaking ahead of the World Cup Phil Scolari has said that he is worried about Crisitano Ronaldo and the way he reacts to referee decisions and the opposition.
"Cristiano Ronaldo worries me, because the majority of our opponents provoke Cristiano and he does not know how to deal with it."
He added: "He must keep it in his head not to react in this way. Our opponents know that if they get at Cristiano he will react this way.
"I want him to bear this in mind. He is part of a squad. We are trying to show him the difficulties he will have in the next few days. Of course I am worried about him.
"We're trying to make him understand referees do not always penalise fouls. Cristiano has a good character and listens to his team-mates. I think he will change."
