2. Diego Maradona
Not too long after causing controversy for his ‘hand of God’ moment against England back in the 1986 FIFA World Cup Quarter Final, it became known that Maradona had a Cocaine addiction from the mid 1980’s until 2004. Whilst playing for Napoli he had a serious addiction which caused the Argentine to later be banned from playing football for 15 months after failing a drugs test in 1991. Maradona was also given a two year and ten month suspended jail sentence in 1998 after shooting some journalists outside his home with an air rifle.
