"I need to win more battles on the field. I need to become more aggressive and to show more malice.
"Just like Arsenal's Robert Pires, people say I'm too much of a nice guy and they're not wrong. I am still too introverted. Even when I get stuck in, using all my willpower, I still don't win any battles."
