Real Madrid coach Zinedine Zidane confesses he's "not proud" of his infamous headbutt during the 2006 World Cup.

Zidane saw his last match end in ignominy when sent off for headbutting Italy defender Marco Materazzi in the chest during the 2006 Final.

“I am not proud. I am not proud of what I did," confessed Zidane to Telefoot on Sunday.

“I apologised to all the young people, to everyone, to all those Coaches who make football different. But it is part of my career, of my life, of the things that are not pleasant, but you have to accept and absorb them."
