Floyd Mayweather vs Manny Pacquiao could happen twice in a year, says Bob Arum http://www.dailymail.co.uk/sport/boxi... After decades of waiting for the fight the whole world wants to see, it now seems that Floyd Mayweather versus Manny Pacquiao could happen twice in one year. Bob Arum, the PacMan’s promoter, is convinced that the two greatest pound-for-pound boxers on the planet will finally get it on in 2015. Arum also believes that the carrot of a double-your-money re-match a few months later will clinch at last a deal which has proved more elusive than the Scarlet Pimpernel.
