A controversial figure off the field, Mutu received widespread attention following a positive test for cocaine while playing for Chelsea in 2005, which resulted in his immediate release from the club, a subsequent 7 month ban from the Football Association, and Mutu later being ordered to pay £15.2 million in damages to his former employers, the largest financial penalty in FIFA history. He has unsuccessfully tried to appeal the fine numerous times, and was banned for a second time in 2010 following a positive test for sibutramine while at Fiorentina.
