Zinedine Zidane
In 2006, Zidane announced that he would retire after the World Cup. Zidane was famous for headbutting Marco Materazzi in the chest during the 2006 FIFA World Cup final at the 110th minute of extra time and was sent off with a red card. France eventually lost 5-3 in penalties to Italy and got second place. This incident was widely known as the Zidane headbutt. There is even a sculpture of it in Doha, Qatar.
