^The infamous ZIZOU's headbutt.
Zinedine Zidane's agent says the France captain headbutted Marco Materazzi in Sunday's World Cup final because the Italian made a "very serious" comment.
Zidane appeared to react to something that was said and was dismissed for his violent charge into his opponent.
Sources in France say it is believed Materazzi insulted Zidane's family.
Migliaccio, who spoke to Zidane early on Monday morning, added that Zidane did not elaborate on what Materazzi said.
"I don't know. Zinedine didn't want to talk about it but it will all come out in the next week," he said.
"He is a man who normally lets things wash over him but on Sunday night something exploded inside him.
"He was very disappointed and sad. He didn't want it to end this way."
