Italy defender Marco Materazzi has been asked to explain his conduct in the incident that saw Zinedine Zidane sent off for violent conduct in Sunday’s World Cup final.

France skipper Zinedine Zidane was sent off in extra-time in Berlin for headbutting Materazzi in the chest. The French skipper has since said he reacted to provocation from his opponent.

Fifa has summoned the players to attend a hearing of its disciplinary committee on Thursday 20 July in Zurich.

A Fifa statement confirmed: “The decision was taken following claims made by French player Zinedine Zidane.”

Zidane has the right to make a written statement, which must be submitted by Tuesday 18 July. Materazzi will then be given a copy of the statement so he can respond to the allegations.

Materazzi has admitted insulting Zidane, but denied referring to his opponent’s mother or making racist comments.
