3. Zidane headbutt

The stage was set for a fairy-tale end to the glittering career of Zinedine Zidane. Here was one of the greatest players of all time playing in his last ever game. One more win and he would be lifting the World Cup. When Italy and France were level at 1-1 after 90 minutes, the game went into extra-time, and this was where the tale took a wicked turn. Zidane, apparently provoked by Marco Materazzi, walked calmly over to the Italian defender. He then rammed his head into Materazzi's chest, knocking him to the ground. France's captain was sent off, his team would lose on penalties and Zidane's extraordinary career had an extraordinary finish.
