Can't go back in time: Zidane on headbutt incident in 2006 WC final

Ex-French footballer Zinedine Zidane, speaking about headbutting Marco Materazzi in the 2006 World Cup final, said that he's not proud of what happened. "I think (former French teammate Bixente) Lizarazu is the only one who could've contained me at that moment...but you can't go back in time," he added. "There are always difficult moments...that was one of those," Zidane stated.
