Floyd Mayweather's share of the fight with Manny Pacquiao, the highest-grossing fight in history, is estimated to be €214 million.
Now Mayweather is cranking up the interest in what he says will be his last ever fight, what he calls "the Mayweather sweepstakes", in September. The 38-year-old is anxious to retire unbeaten but he knows that his reputation will suffer if he doesn't fight a credible opponent. He also knows that the public won't pay to see a non-contest.
Although his rare Ferrari Enzo is on the market for $3.8 million, Mayweather is not cash-strapped. Asked who he's going to fight, Mayweather said: "It all depends on how I feel." England's Amir Khan has been jockeying for position in the hope of meeting Mayweather (inset).
He recently defeated Chris Algieri, who Pacquiao fought before fighting Mayweather, but despite having had three loses in his career, Khan's speed may be considered too much of a threat for Mayweather who insists he won't be fighting the Bolton boxer.
