French legend Zinedine Zidane admits he regrets headbutting Inter Milan defender Marco Materazzi. The pair clashed in the 2006 World Cup final, which saw former Juventus ace Zidane sent-off in the final game of his glittering career.

In a book by journalist Besma Lahouri called 'The Hidden Face of Zidane', it is revealed that Zidane told his cousin that he regrets his actions on that fateful day.

It is reported that when talking to his cousin Akbou in Algeria, Zidane said: "Don't ever say I did well when I head-butted Materazzi. I didn't do the right thing and I am sorry for that."
