Manny Pacquiao plans to fight Shane Mosley in his next bout on May 7 in Las Vegas.

Promoter Bob Arum told The Associated Press last week that the deal will be done after Mosley’s lawyers approve the final paperwork for the WBO welterweight title fight at the MGM Grand Garden Arena.

Arum says Pacquiao chose the bout because Mosley is the most accomplished and famous boxer in the field of candidates, which included Juan Manuel Marquez and welterweight champion Andre Berto.

“He’s the most recognisable name, and it’s a difficult fight for him,” said Arum, who met with Pacquiao in the Philippines last week. “People are also saying, ‘Well, why hasn’t he fought an African-American fighter?’ He’s doing that, but mostly it’s because Mosley is the biggest name.”

Pacquiao also realises a potential superbout with Floyd Mayweather Jr is likely still impossible because of the Mayweather family’s various legal troubles.

Pacquiao (52-3-2, 38 KOs) is on top of the boxing world after trouncing Antonio Margarito in a one-sided decision in Texas on November 13. The 32-year-old Filipino congressman has won 13 straight fights while claiming world titles in an astonishing eight weight classes, most recently taking the WBC light middleweight belt with his win over Margarito.

Arum realises he could have trouble selling a fight against a 39-year-old opponent who will be nearly two-and-half years removed from his last victory when he faces Pacquiao, but believes Mosley’s skill and speed will challenge Pacquiao.

“That was obviously a negative, but Shane Mosley is capable of doing great things,” Arum said.

Mosley (46-6-1, 39 KOs) is near the tailend of a remarkable career that began in 1993. The former three-division champion has won just two of his past five fights, getting walloped by Mayweather in an unanimous decision last May before fighting to a dull draw with Sergio Mora on September 18.

The deal further cements Mosley’s acrimonious split from Golden Boy, Oscar De La Hoya’s promotional company.
