American boxing great Mike Tyson’s former bodyguard and chauffeur Rudy Gonzalez had revealed that the former heavyweight champion would have sex with groupies before his fights in order to control his anger. Gonzalez watched the then 20-year-old beat Trevor Berbick on November 22, 1986 to become the youngest heavyweight champion in history of the sport.

According to The Sun, recalling Tyson’s mindset and talent on the 35th anniversary of that feat, Gonzalez said: “One of the greatest secrets with Mike was that he needed to have sex in the dressing room before fights. I would have to find a groupie, it did not matter who it was. He’d say ‘if I do not get l**d I will kill this guy right now.’ Mike had to get l**d to disengage some of the strength he had. So I had girls tucked away in bathrooms and changing rooms.”
