Floyd Mayweather Jr. has said that he is seriously preparing for his fight against Andre Berto in Las Vegas.
In a press conference, Mayweather said that Berto had nothing to lose, and added that when a person has nothing to lose, it makes the person work harder, Sports24 reports.
The 38-year-old boxer stated that he is prepared and in top shape for the fight, adding that he was not going overlook Berto.
The American boxer will square off against former-welterweight champion Berto on September 12 in Las Vegas in his attempt to equal Rocky Marciano's 49-fight undefeated streak.
Earlier, Mayweather insisted that Berto was a worthy contender who would push him to the limit.
