Manny Pacquiao's promoter Bob Arum, who says the 34-year-old will box again on 12 April in the USA, is hopeful a fight with Mayweather will happen.

"It's a fight that should happen - and where there's a will, there is a way," Arum said.

Pacquiao, who was fighting for the first time since being knocked out by Juan Manuel Marquez nearly a year ago, put on a dominant display to beat Rios by unanimous points decision.

He continually stunned his brave opponent, with the American in desperate trouble in the seventh and 12th rounds.
