The question is,what the heck did Materazzi say because ZZ smiled at first and was walking away.but you can clearly see Materazzi's lips moving! Then, ZZ turned around and dang,what a headbutt!!! I'm not excusing what ZZ did,but it's strange that Materazzi does not want to talk about it(avoided it in an interview),showing maybe that he is not innocent?
I agree BK,had technology not been as sophisticated as it is,ZZ would have got away with it. And by the way,I totally disagree,I think it's a poor way to end a glittering career but it doe not mean we look at his career in shame at all,he was and is one of the greatest players of all time. Maybe he thought,it's my last match,they'll let me off?
