Photos: Manny Pacquiao disses Floyd Mayweather on Twitter, then deletes the tweet

Manny Pacquiao. All-time great boxer, politician, and now, a Twitter savage.

Pacquiao took a well-placed shot at Floyd Mayweather on Saturday morning in a since-deleted tweet, once again calling out his rival for the conservative style the American deployed in their 2015 superfight.

In what was billed as the "Fight of the Century," Mayweather won by unanimous decision, but many felt the much-hyped bout fell far short of expectations in part due to "Money" opting against any aggressive tactics.

Mayweather has promised fans will get their money's worth for Saturday's fight against Conor McGregor, proclaiming the fight won't go the distance.
