Cristiano Ronaldo says he's not satisfied with his game at Real Madrid. The former Manchester United star insists he still has a lot of room for improvement.
"If you think you know everything, you will never succeed," declared Ronaldo. "We must always improve.
"And that's what I try to do. Everything I did at 18 or 19 years of age I still do now. So I'm always evolving and learning new things.
"Now I'm more mature as a player. The experience gives you stability and helps you be more relaxed on the field.
"I try to learn game by game."
