WBC welterweight champion Floyd Mayweather Jr. says his next opponent will be decided within a week. One thing's for sure, it's not Manny Pacquiao.

The undefeated Mayweather, now 45-0 after dominating Canelo Alvarez for a majority decision in September, also passed off Pacquiao's renewed attempts at making their mega-fight happen as desperation because of the Filipino star's tax issues.

Mayweather said of Pacquiao "two losses and tax problems later, now he all of a sudden want to say: `You know what? I'd do anything to make the fight happen.'"
