Mayweather: Pacquiao declining and desperate
Pacquiao recently made the admission that he would be content to take 45% of the money if a bout was agreed between the pair, with the majority going to Mayweather.
The revelation came in the wake of Pacquiao's defeat to Timothy Bradley, which followed a disputed points triumph over Juan Manuel Marquez, who he meets again on December 8.
"In my opinion, Manny Pacquiao is desperate," Mayweather told fighthype.com. "He doesn't make his own decisions, because Manny Pacquiao has a boss, his promoter [Bob Arum], who makes his decisions.
"Once you take a loss and you're on the decline... Listen, Manny Pacquiao, whether he got cheated or not [against Bradley], his stock drops enormously after taking a loss. No matter how you took a loss, you took a loss."
The distribution of money proved an insurmountable hurdle during the most recent round of negotiations between Mayweather and Pacquiao. Previously, a dispute over the timing of blood tests put paid to any agreement.
