15. Luis Suarez racially abuses Patrice Evra during a game.
Punishment: 8-match suspension, £40,000 fine
World football has long been plagued with ugly instances of racism. While FIFA and the English FA have made every attempt to eradicate it from the stands, it's much harder for them to control the minds of the players on the pitch. Luis Suarez's abuse of Manchester United's Patrice Evra drives the point home, as the talented Uruguayan striker laid into the French defender with various racial epithets throughout the match. Months later, Suarez did himself no favors in the court of public opinion when he refused to shake Evra's hand in the standard pre-match handshake line.
