From the Guardian,
According to the BBC, Materazzi said, “I wish an ugly death to you and all your family,” and then told Zidane to “go fuck yourself”.
If you ask me, this is a sad end to Zidane’s career (he announced that this would be the last he would play in competitive football), and though I can understand him getting angry, I do not condone his reaction. Unfortunately, Materazzi got just what he wanted by making Zidane angry. It’s sad, and it frustrates me that one of the best players we’ve ever seen has to go out this way.
Au revoir Zizou, vous Ãªtes un dieu toujours.
UPDATE: Each passing day involves another lip-reading expert making another decision on this.
UPDATE 2: Zidane’s explained what happened.
