Mayfield, 33, was one of three names alongside British fighter Amir Khan being considered by for what is being billed as Mayweather’s final fight despite having won just one of his last three fights.
Mayweather eventually settled for ex-WBC title holder Berto for his latest pay-per-view offering in Las Vegas and Mayfield has revealed his initial shock at being named by the four-belt champion at a media gathering back in June.
“I was certainly surprised due to the fact that I’m not in the top five in the world and I wasn’t expecting anything like that,” Mayfield exclusively told World Boxing News over the phone on Wednesday.
“I think Floyd chose the easier opponent, but I’m not saying by any means that Andre Berto is an easy opponent. I just think it will be less of a challenge than it would be with me as I believe Andre Berto will be a cakewalk – a walk in the park.”
“I’m not saying Berto doesn’t have a chance, but anyone who boxes Floyd doesn’t have a chance. Even if you look at the pound for pound best in the world, Manny Pacquiao didn’t even have a chance. Floyd just used his defense and the way he likes to stay elusive. So, unless you’re coming forward against Floyd Mayweather you don’t have a chance.
Asked whether he believed Khan would have been more of a test than Berto for Mayweather, Mayfield replied: “I think Amir would not have been a tougher test, but certainly a challenge because of his speed and the fact that he is unorthodox.
“But pretty much everyone that boxes Floyd in the same kind of style and you don’t have any sort of strong pressure then it’s going to be the same situation that we saw with Pacquiao.
“I do think Virgil Hunter and Berto would have certainly worked out a plan to move forward though,” he added.
‘Hard Hitta’ is currently weighing up his own options following his eight round victory over Michael Balasi in San Francisco last November which pushed the former fringe WBO title holder’s record to 19-2-1.
