Boxing: Mega clash is one between fighters at the prime of their careers, says Mayweather

LAS VEGAS (AFP) - Floyd Mayweather says it will be two "hall-of-famers" in their prime when he and Manny Pacquiao clash in the richest fight in boxing history on May 2 at the MGM Hotel.

In the only Las Vegas news conference he is giving ahead of fight week, Mayweather said on Tuesday that he is not worried about spoiling his perfect 47-0 record.

"He's a future hall-of-famer. I am a future hall-of-famer and we are meeting at the pinnacle of our careers," Mayweather said. "From the match-up, it is going to be a very exciting fight.

"Our styles are totally different. I fight with smarts. Every move is calculated. Every move is thought about."

He also discussed how his training is progressing, Pacquiao's strengths and weaknesses, retirement and revealed that the thrill of boxing is gone and that at this point in his career, it just feels like a job.

"No. I don't enjoy it like I once did," said Mayweather, who was fashionably late for his workout session. "It is at a point where it is business. It is my job. I go to the gym. I train. I know what I have to do," he added, speaking from a tent outside his Las Vegas gym located in the middle of the desert city's Chinatown district.
