But Materazzi told Gazzetta dello Sport that Zidane's sister was the subject.
He said: "I was tugging his shirt, he said to me 'if you want my shirt so much I'll give it to you afterwards,' I answered that I'd prefer his sister."
Materazzi added: "It's not a particularly nice thing to say, I recognise that. But loads of players say worse things.
"I didn't even know he had a sister before all this happened."
Materazzi was later handed a two-match ban from world governing body Fifa, while Zidane was banned for three games and fined £3,260.
Zidane, who has since retired from football, has never specified what Materazzi said to him and has refused to apologise to his opponent.
