Floyd Mayweather is happy to admit his undefeated record has been partly built on handpicking opponents who didn't always provide the toughest fights but did help him become the world's best paid athlete.
"Sometimes they say, 'Well, Floyd Mayweather's opponents was handpicked.' That's a good thing," Mayweather said in a conference call to promote Saturday's eagerly-awaited world title fight against Mexico's WBC and WBA super welterweight champion Saul "Canelo" Alvarez.
"I commend my team ... when I sit back and I think about my career, I say 'you know what? I had a cool career. I didn't take any punishment'.
"If they say these guys were handpicked, they was handpicked to make $40 and $50 and $60 million, then you know what? Keep handpicking them. If they're going to keep paying, keep handpicking them."
Mayweather, who Forbes magazine lists as the world's highest paid athlete, has been criticised for dodging a potential mega fight with Filipino superstar Manny Pacquiao.
The two have tried several times over the past few years to get the deal done for what would likely be the biggest and most lucrative fight in boxing history.
But each time negotiations broke down when they couldn't come to terms on a variety of issues, including drug testing and share of the revenue and purses.
The fight with Alvarez is the second in Mayweather's six-bout, 30-month contract with American cable network Showtime that could pay him more than $US200 million. After Mayweather beat Robert Guerrero in May, he said he wanted to fight again in September - marking the first time since 2007 he will be in the ring twice in a calendar year.
Mayweather's guaranteed purse for the Alvarez fight is reported to be a record $41 million which would surpass the previous record of $32 million he received for fighting Guerrero.
Organizers are also hoping that this fight will eclipse the 2.44 million record pay-per-view sales and sales of more than $130 million racked up by the Mayweather and Oscar de la Hoya fight in 2007. Mayweather will also get a cut of the pay-per-view money on top of his guaranteed purse.
Mayweather, who is undefeated in 44 fights, says he will take nothing for granted when he faces Alvarez in a 12-round showdown of unbeaten fighters at the MGM Grand Hotel.
"I am not overlooking this guy," said Mayweather. "In Mexico he is a young rock star and everybody that they put in front of him he was able to go out there and do his job.
"I am pushing myself to the limit right now."
The last time Mayweather stopped an opponent inside the distance was two years ago and that came when Victor Ortiz lowered both his hands and was looking at the referee for a ruling. Mayweather seized the moment and hit Ortiz with a combination of punches that floored Ortiz.
Since then, Mayweather has won 12-round decisions over Miguel Cotto in May 2012 and Guerrero.
Saturday's fight will be contested at 152 pounds with Alvarez's super welterweight titles on the line. Alvarez (42-0-1) is a 154-pound champion and Mayweather usually fights at 147 pounds.
