Zinedine Zidane, had an incredible career and ended it in an incredible shame as he was sent off during extra time in the 2006 World Cup Final!
The French captain head-butted Italian Marco Materazzi in the solar plexus after apparently hearing something said to him as shown in the following photo.
This left the referee no choice but to show him the red card. Shame on you Zidane, you were poised to end your career on a high note with the MVP award after your penalty kick goal in the sixth minute, but you couldn't control your temper. You brought shame on yourself, your team, and your country during the world wide broadcast. The world awaits your apology!
