- Floyd Mayweather Jnr v Miguel Cotto
Pacquiao's win over Cotto doesn't count - Mayweather
Mayweather, who meets Cotto on May 5 in Las Vegas, claims the Filipino's 12th-round stoppage triumph should not be a stain on Cotto's record because the bout took place at a catch-weight of 145lbs.
The unbeaten American is climbing from welterweight to meet Cotto, the WBA light-middleweight champion, at his preferred size.
"You have a guy Miguel Cotto. He has two losses, but one of his losses is to a guy at a catch-weight, where he wasn't 100%," Mayweather told boxingscene.com.
"And you have another loss to a guy [Antonio Margarito] who was caught cheating in the sport. I'm [thinking] that I'm facing a guy who's undefeated.
"He faced Antonio Margarito, a guy who everybody said I was scared of, and he got caught cheating. Now you got Manny Pacquiao, a guy who fought Miguel Cotto at a catch-weight.
"So you have one guy who cheating and one guy who fought at a catch-weight. I wanted to fight Miguel Cotto at 154lbs [light-middleweight] because I wanted to fight the best Miguel Cotto."
