The 'headbutt' incident to be investigated by FIFA

FIFA are having an investigation into the circumstances surrounding France captain Zinedine Zidane's head-butt on Italy's Marco Materazzi during the World Cup final.

There has been a lot said by the media and it is hard to think what might have happened, people have said that Materazzi insulted Zidane's mother or sister or that he called Zidane a terrorist!

Materazzi denies this saying that he did throw an insult but it is one that is heard on the pitch dozens of times.

UPDATE: On a talkshow Zidane said that Materazzi said something that involved his mother and sister and that he repeated the phrase 3 times!
Who knows if this is true, I wonder if we will ever find out??

It is all quite contraversial, what do you think happened and what do you think might happen??
