What Berto, Berto’s trainer, Virgil Hunter, George Groves, Jhonny Gonzalez and Mayweather Promotions CEO Leonard Ellerbe said Friday:

"At the end of the day, this fight was supposed to happen two or three times. Situations with me not taking care of myself and not taking opponents seriously caused it to happen. But styles make fights and we'll see what the boxing fans say Sept. 12," Berto said.

"I know that I'm still the same guy who people thought could have given Floyd problems a couple years ago.  Victor Ortiz and Robert Guerrero both got fights with Floyd because they beat me. There must be something to that. They said 'if he did something to Berto, he should get a shot at Floyd.'"
