3. Rio Ferdinand
His name is Rio and he's so forgetful that he probably needs reminding of it every morning. On September 23, 2003, drug testers arrived at Manchester United's Carrington training complex for routine but mandatory testing. Rio was on the list, but went shopping instead. He was banned for eight months rather than two years, which would have been the case had the FA not accepted that he was forgetful rather than evasive.
