Floyd Mayweather has written off the chances of opponent Saul Alvarez before the two take to the ring in Las Vegas on Saturday night.
The two unbeaten fighters are contesting the WBC and WBA light-middleweight titles at the MGM Grand, with the American the strong favourite.
Mayweather is guaranteed a record £26.4m for the fight, which may also become the most lucrative pay-per-view event in history.
And, the 36-year-old has dismissed his 23-year-old Mexican opponent ahead of the bout, claiming Alvarez is simply outmatched against a fighter of his ability.
"He knows he's facing Floyd Mayweather, I'm facing just another opponent," said five-weight world champion Mayweather.
"If the game-plan is to keep up pressure, I can handle it. If the game-plan is to out-box me, nobody can out-box me. You have to be able to out-match me mentally, and I'm the strongest mental fighter in the sport of boxing. I've been here before so I know what it takes.
"He's 42-0 [Alvarez also has one draw], but he hasn't faced 42 Floyd Mayweathers, otherwise he'd be 0-42. I'm at the pinnacle. I'm the face of boxing."
Mayweather has an unblemished professional record of 44-0 in 17-years in boxing, and fight-promoters Golden Boy are expecting two million American homes will pay £47.50 to watch him in action.
That would eclipse the current richest fight; Mayweather's 2007 victory over Oscar de la Hoya, which was bought by 2.7m homes.
"Saturday could be a $200m (£126.7m) night," said Golden Boy chief Richard Schaefer.
"Boxing is hardly a dying sport."
Saturday promises to be a fantastic night of boxing, with Danny Garcia's bout against Lucas Matthysse a wonderful starter before the main event.
