The former Arsenal and Barcelona star never seems to have a happy expression on his face no matter what happens on the pitch but he says that stems from watching the NBA's greatest - Michael Jordan - who had a commitment and a will to win whatever it took.
"I grew up watching Michael Jordan. When have you seen Michael Jordan being happy once?" he said in an interview with Sports Illustrated.
"Even when he hits a basket at the buzzer. I'm just saying. It's funny because people are making me laugh usually when I hear that.
"Michael Jordan won everything and anything. Like a warm-up game or whatever game it was, I never saw Michael Jordan smile. That's the attitude you have and when I'm on the field I'm not here to please anyone.
"When people talk about commitment and all of that - if I don't have commitment I go home. What am I looking for here?
"I've said it so many times, the day I have no commitment left is the day I go. If people still question a guy like (David) Beckham or a guy like me - do you think a guy like me goes on the field and wants to look bad?"
