Zinedine Zidane

http://www.worldsoccerinfo.com/ As Zidane and Italy defender Marco Materazzi were jogging up the pitch in close proximity of each other, they briefly exchanged words after Materazzi was seen tugging at Zidane's jersey before Zidane began to walk away from him. Moments later, Zidane suddenly stopped, turned around and rammed his head into Materazzi's chest, knocking him to the ground.
