Ronaldo heads for exit door
"It [moving to Real] is a dream, a step forward, you can call it what you want," Ronaldo said.
"For me it is a great opportunity and, as Scolari says, that train passes by only once and we have to take advantage of it.
"That is why he took advantage of his change. Other people have to take advantage of opportunities, too."
Asked whether he was concerned his actions would upset United manager Sir Alex Ferguson the winger added: "It is my opinion. That is why I don't mind if people get upset.
"It is my decision. It is what I want. I don't know what I have to say to him. I have to say what I want and what I think."
