8. Didier Zokora & Emre Belozoglu
Source: Goal
Zokora and Belozoglu are competitive pair with successful careers. In 2012, while playing in Turkey, Belozoglu yelled a racial slur to Zokora, and Zokora responded with his own aggressive challenges. Belozoglu, with a history of being accused of racial abuse, was sentenced to two months in prison for the incident. The two have not made peace.
