Floyd Mayweather Jnr challenges Manny Pacquiao to Las Vegas fight on Twitter Mayweather called Pacquiao out on the social network site Twitter. "Manny Pacquiao I'm calling you out, let's fight May 5th and give the world what they want to see," Mayweather tweeted. My jail sentence was pushed back because the date was locked in. Step up punk. Richard Schaefer, CEO of Golden Boy, told Telegraph Sport: "Why do people continue to think that Floyd is avoiding Manny Pacquiao. Believe me, it is the other way around. Bob Arum [Pacquiao's promoter] categorically does not want Pacquiao to face Mayweather. Believe it. He wants to keep the Pacquiao bandwagon moving. It is time that people realised Floyd would definitely fight Manny. The problem is that there is only one winner in the fight: Floyd Mayweather. And Bob Arum knows it.
