It's worth noting however that Pacquiao has seen one of his compatriots call out Mayweather in what maybe one of the most bizarre challenges in recent memory.
The Filipino fighter who has, publicly, challenged Mayweather is Light Middleweight veteran Dennis Laurente (48-5-5, 29).
For those international fans out there asking "Who?" Laurente is the #13 WBC ranked Light Middleweight and at 37 is likely looking for a retirement fund. His attempt at luring Mayweather into the ring is likely to be the boxing equivalent of pissing into the wind with absolutely no chance that Mayweather will take any notice, in fact we'd be very shocked if Mayweather even knew of the challenge.
