Thus far, we have heard the trash talk commence with regards to the upcoming mega bout between Floyd Mayweather Jr. and Manny Pacquiao. Both camps have had their share of firing at the other and the latest one comes from Floyd Mayweather Sr.

For Floyd Sr., he believes that Pacquiao trainer Freddie Roach is worried on how his boy will fare against his son. As always, he is someone who doesn't think highly of the Filipino boxer as well as his handlers.

Floyd Sr. further adds that he never gets worried when his son enters the ring. He considered the upcoming battle just like any other bout and believes that Roach is firing his shots because he is confused and worried at how the Filipino boxer would be able to hurdle his undefeated boxer-son.

Floyd Mayweather Sr. is no stranger to trash talk, especially when it comes to Manny Pacquiao. He had already hurled accusations before that Pacquiao is taking performance-enhancing drugs (PEDs).

Roach on the other hand has repeatedly stated that they have Floyd right where they want him. The long-time trainer has kept Pacquiao's training in closed doors and reveals that they have the ultimate master plan to finally hand Mayweather Jr. his first boxing career loss.

The word war between both camps is expected to continue until the fight is officially here. Mayweather and Roach have been notorious for taking barbs at their fighter's opponents and with both going head-to-head, expect a colorful and heated exchange as the days pass.

Mayweather is a 2-1 favorite over Pacquiao although there are some who believe that a likely fighter to end Mayweather's dominance would be the multi-awarded Filipino boxer.

Both fighters are under intense training as we speak, and hopefully these barbs do not become distractions as both fighter prime themselves up for perhaps one of the biggest bouts of boxing.
