Italian magazine Tv Sorrisi e Canzoni has revealed what Marco Materazzi really told Zinedine Zidane during the 2006 World Cup final, which led to the French star headbutting the defender. After Zidane had offered to bring him his shirt after the match, Materazzi replied: Id prefer you brought me your sister, that b*tch. Materazzi clarified: The excerpt in Tv Sorrisi e Canzoni is not part of an interview as claimed by the paper, but taken from my autobiography, which will come out in September. I will only speak about the book after August 31st, when I will officially present it in Milan. Anything said about it before that day has to be considered as not authorised by me."
