Pacquiao tells Mayweather: “Step up and fight me”

The seemingly never-ending war of words between Manny Pacquiao and Floyd Mayweather Jr looks set to run and run and run after the Filipino hit back following the American's taunts on Instagram.

Mayweather had posted a video on the site of Pacquiao being knocked out by Juan Manuel Marquez, with "Another one bites the dust" playing in the background. But in a press conference in Makati, Pacquiao threw down the gauntlet to his potential opponent, saying if Mayweather is so confident, he should have no problem making the fight happen. "Pinost niya, dapat lumaban na siya. Madali pala akong mapatulog (He should step up and fight me since I am easy to knock out)," he said. We're really hoping this fight happens sooner rather than later, verbal uppercuts can get tiresome after a while. http://instagram.com/p/v2vvAqx3RH/?modal=true
