Italy defender Marco Materazzi's World Cup final confrontation with France's Zinedine Zidane prompted a series of songs, games and jokes on the internet and has now resulted in the Inter Milan centre-half writing a book of jokes about the incident.

What I really told Zidane will be published this month by Italian publishing house Mondadori with all profits going to the United Nations Children's Fund.

Materazzi's words to the French midfielder in extra-time of July's final in Berlin led to Zidane head-butting him in the chest and being sent off in his last game.

Down to 10 men, France lost the game on penalties.

After weeks of speculation Materazzi said in September that it was a reference to Zidane's sister that prompted the violent reaction from the former European Player of the Year.

Italian media reports said the book contains 249 'jokey' suggestions as to what Materazzi may have said during their verbal exchange.

Among the suggestions put forward by Materazzi in the book are: "French philosophy has been rubbish since (Michel) Foucault died" and "Where exactly is the sternum?".
