In an interview with Zoo magazine he said: "Sometimes he shakes me and he shouts at me,"
"It's normal. He's like my mother or my father, he gives me limits and targets. But he is fair.
"At half-time during games, he has shouted at me a few times, but always to improve me. People say he's mellowed, but he can still get angry - believe me!
"But the work I have done with Sir Alex has been very helpful. I speak almost every day with him. He knows how to create a good atmosphere.
"Before every game the manager tells me 'Cristiano, enjoy yourself, use your skills'. I listen to that. I like dribbling - it's my style.
