I do not believe anyone could remain calm if their mother who is sick in hospital was insulted as well as their sister called a prostitute but in more vulgar language. What he did was not good, but he's human.
On the pitch I hear a lot of things, as the Italian said a lot gets said. But I have never heard someone insult anothers family and if they did it would surely cause an altercation. Insult someones play or even them personally, but not their family. What was said is a disgrace to all of Italy and puts a cloud over the entire World Cup, the reaction from Zidane surely adds to that but there was a reason for it. I was very proud of Zidane the way he stood up and did an interview explaining why he did what he did and stating very clearly how he felt about the incident, as well as apologizing to the children watching.
Materazzi showed his complete lack of class by not apologizing for his words or his obvious dive after the fact (I love the way his legs collapsed backwards before his body does despite being hit in the chest, pure magic). Do not get me wrong, a red card was in order for Zidane, but after the fact Materazzi could of apologized, instead he insists what he said is just one of those things that come out. Since he's been an awful footballer up to a very recent point, he was transferred out of the EPL to Seria A I believe and found his feet their, unless he becomes a much better player I am sure he will be fittingly remebered for this incident above all else. Zidane will not.
It may be of note that I am an England fan and a Manchester Utd fan through and through and I have no love for Henry or that lousy keeper Bartez. I was priorly impartial to either team and Italy did deserve to win, but what Materazzi did and how he continues to handle it is shameless and embarassing.
