When they write the history of football and look at the pantheon of heroes, Zidane's will rank up with the great names (although slightly tarnished by this incident) whereas Matarazzi will only be remembered for his one goal and his attempts to bring Zidane down.
I would agree EXCEPT that this isn't the first time Zidane has done something like this. Admittedly, I'm not the world's biggest football fan, but isn't this the same player that stomped on another player in '98? This is obviously someone who has issues, not someone who accidently lost it one time...
