Floyd Mayweather has written off Saul Alvarez as just "another stepping stone, another opponent" ahead of their super-welterweight title fight in Las Vegas on Saturday.

The five-division champion will put his unbeaten status on the line when he challenges the young Mexican for his WBC and WBA super-welterweight belts.

"If the game plan is to keep 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. I've been here before, so I know what it takes. I'm at the pinnacle. I'm the face of boxing. September 14 is just another stepping stone; another opponent to me. He knows he's facing Floyd Mayweather. I'm facing just another opponent."

For his part, Alvarez is excited about the prospect of becoming the first professional to beat Mayweather, especially because the fight will be held on Mexican Independence weekend.

"I don't care about his record," said the Guadalajara-born Alvarez, whose record is 42-0-1, with 30 knockouts. "I'm not coming to make a good fight; I'm coming to win. When you fight Floyd you have to be ready for every aspect. You have to be able to adjust mentally as well as physically. I have to be very, very smart and ready to change my plan at any time. I've studied him. I know his style and I know what he's going to do. I'm confident I will win because I know everything about him. I've prepared for everything."

Earlier this week on BoxingScene.com, it was reported that Mayweather tried to get Canelo down to the welterweight limit of 147-pounds and then a catch-weight of 150-pounds. Canelo rejected both of those requests and agreed to come down to a weight of 152-pounds.

Canelo also said Mayweather tried to include a "rehydration clause" in the fight contract, where Canelo would be unable to weigh above a certain number on the day of the fight. Canelo, who rehydrates to more than 170-pounds on the day of the fight, rejected that clause.

"They came up with a second-day weigh-in. They wanted to do a second-day weigh-in and limit what I cold weigh the second day, and I wouldn't agree to that. And then they tried to force me to stay quiet and to not mention it, and that's why we didn't say anything. And we haven't said anything until now," Canelo said.

"You'll see how I do it. You'll see how I beat him. I'm calm and I'm just ready to fight. I'm ready for the best Floyd possible."
