Nearly every great fighter in boxing history has suffered a loss. Very few fighters walked away undefeated. Fighters like Muhammad Ali, Mike Tyson, Sugar Ray Leonard, Roy Jones Jr., George Foreman, Sugar Ray Robinson and Marvin Hagler were all perceived to be invincible at certain points of their respective careers. All of them suffered defeats.

On May 3rd at the MGM Grand in Las Vegas, Garcia's fighter Marcos Maidana will face Mayweather in a welterweight unification on Showtime Pay-Per-View.

"Everyone thinks beating Floyd is impossible, but there will come a time where he's going to have to lose. For this fight, we are going to train hard. Maidana has the heart, the punch, and he won't be lacking anything [in training camp]. We are going to enter [this fight] with every desire to win," Garcia said.

"Everybody thought that Broner was going to get the win over Maidana. Broner was the next Mayweather, and Maidana came to the United States and not only did he beat him - he humiliated him."
