London, Feb. 4 : Manchester United star Cristiano Ronaldo has said that he cannot play at his best unless he is being booed.

According to The Sin, he has got so used to abuse from opposition fans, that without it, he gets paranoid.

"It's normal for me now. If it doesn't happen, I'm thinking, `Why aren't they booing?' It's part of football. Maybe they think if they boo I'll lose my concentration - but it doesn't happen because I like it," Ronaldo said.

Ronaldo first became football's public enemy for his diving, which he has since eradicated from his game. Now, he gets booed because he is so good that he can destroy teams on his own.

And he aims to continue doing that. Ronaldo, with 14 goals this season, is not giving up on the idea until it is mathematically impossible. (ANI)
