I don't know what he was thinking. I also don't doubt for a second that Materazzi said something awful to him, but that doesn't justify it.
In some ways this World Cup was a big disappointment. Obviously partly that is because England woefully underperformed and I'm an England fan, but so did so many others, the Brazilians collectively did for example as doczinn says.
But also some of the less pleasant aspects of the game rose to the surface too often - McBride got a faceful of elbow, Carvalhao got a groinful of boot, the Australians were robbed by a dive, Cristiano Ronaldo was Cristiano Ronaldo and the World Cup final was decided by penalties.
