Miller, who on Tuesday was disqualified from the Winter Olympics' alpine skiing combined event after a slalom slip-up, believes the pressure to succeed forces some competitors to cheat.

"Sport was born clean and would remain so if it was about just competing for the fun of it, but the media and the public corrupt it because of the pressure they create," the outspoken Miller told the Gazzetta dello Sport.

"Any athlete who isn't doing well is left in the corner, nobody asks for their autograph and they're left out in the cold. However, those who win things are regarded as symbols.

"Fame is like a poison. I don't care for it. I used to have a better life when I was nobody."
