uhm...some facts:
1. italian way to play is never spectacular
2. Materazzi was sent off, and he should have got only a yellow card.
3. Australia plaied 30 minutes 11 against 1o they had a chance to win, and did not win, which does not imply that australia was better then italy, on the contrary it imply the opposite
4. Hiddink, Australias coach, hoped to beat italy with ball possession: everyone knows that with ball possession you can't beat defenders like the italian ones, you need fast play instead; thus Hiddink lost its match
5. In the previous world cup Hiddink was the coach of Korea who sent Italy out thanks to the referee Moreno, who was so dirty that after a while he was banned as a referee
6. The penalty: the player didn't dive, and in fact he is not a forward, he is a defender, so you can't say that he is used to dive. He had fallen down because he suddenlly found the body of another man on his legs.
7. The australian defender perhaps didn't mean to hit the italian player, but unfortunately for him he did, and he also raised his arm a little bit up, enough to stop the italian player, maybe he didn't want to, but he did.
8. According to the rules this is a penalty
9. However, it is one of those penalties that may be given or not...let say not a very clear penalty.
10. Probably the referee wanted to compensate the previous error of sending Materazzi off.
11. Thereferees in this world cup are doing very badly, even yesterday they helped Brasil as much as they could.
12. If you are really used to see players diving, then you must admit that Grosso, the italian player, did not dive, it is clear that he simply had fallen down, but this has nothing to do with cheating: not evryone is able to run with another man between his legs.

All this prove that the italians didn't cheat at all, the only thing we can say is that the refereee was crap, and he made mistakes both for Italy and Australia.

Honestly I like the Australia team (apart from Hiddink who is quite a good coach but not a good loser) and I am sorry that it went out, they semply were unlucky, but this doesn't mean that we cheated, and if you say so, it means that you don't know the meaning of the word "sport"
