Mexico's Juan Manuel Marquez is emerging as the next opponent for WBO welterweight champion Manny Pacquiao - as long as the Filipino defeats Shane Mosley on May 7 in a bout scheduled at the MGM Grand in Las Vegas, Nevada.

In 2004, Marquez and Pacquiao went to a draw despite Marquez being knocked down three times in the first round, and in 2008 Marquez lost a close split decision in their rematch.

"Right now this is the best fight available for Pacquiao and finishes the trilogy," he said.
