It was a headbutt no football fan will ever forget. In the 2006 World Cup Final, Zidane suddenly headbutted Italian midfielder Marco Materazzi in the chest. No one knew what they were talking about on the pitch and why Zidane went furious.
Zidane was sent off after this incident in the 110th minute of the game and Italy finally claimed the cup after beating France in penalty shootout.
The most common version of events was that Materazzi insulted Zidane's mother but the Italian denies that this was the case in a book about his life. "My mother died when I was 15, I would never have insulted his. "I spoke about his sister."
