From Jason Kottke:
The Daily Mail, with corroboration from the Times, has some information on what Marco Materazzi said to Zinedine Zidane to provoke the latter’s career ending headbutt in the 2006 World Cup final (more info on that here). They both hired lip readers to decipher Materazzi’s dialogue before the incident and this is allegedly what he said (translated from the Italian):
Hold on, wait, that one’s not for a nigger like you.
We all know you are the son of a terrorist whore.
So just fuck off.
So it might be fair to say that Materazzi got what he deserved, as did Zidane when he got sent off.
