Zinedine Zidane has admitted he is "not proud" of the headbutt on Marco Materazzi that led to his dismissal in the 2006 World Cup final.
France captain Zidane was shown a red card after headbutting Materazzi during extra-time of the final, which Italy went on to win on penalties.
There was speculation that Zidane landed the headbutt after Materazzi insulted his mother, though the Italy man later claimed that what he said "was in reference to his sister."
The incident was Zidane's final act as a player as he retired immediately after the World Cup, and the Real Madrid coach concedes he let himself down.
"I did not feel proud," Zidane told Telefoot.
"I am not proud of this gesture -- for all these young people, all these coaches, all those volunteers who make football a different thing.
"But it is part of my career, my life. It is one of those things that are not pleasant, we must accept, that we must digest."
