I assume we're not just talking about skill or lack of it as the case may be. I would have to say Diego Maradonna and not just because of his 'hand of god' stunt but because he probably could have won an olympic medal for diving & an oscar for acting. The man had his moments of footballing genius I grant him that but sadly he will always be remembered for bringing the game into disrepute.... Hand of God... Cocaine... Temper Tantrums.... need I go on? I think not.
