Trainer Floyd Mayweather Sr. thinks very little of Manny Pacquiao's string of wins in the aftermath of his devastating knockout loss to Juan Manuel Marquez in 2012.

In Pacquiao's last fight in November 2014, he dropped previously undefeated Chris Algieri six times for a ridiculously one-sided twelve round unanimous decision.

Some saw the outcome as an impressive win for Pacquiao. Others saw a difference in class with Algieri biting off more than he could chew.

Mayweather Sr. thinks so little of Algieri and views him as such a minor threat that he's willing to face him in the ring with one hand.  

"Let me tell you this right here, Algieri was nobody. I could whoop Algieri my damn self with my left hand. I wouldn’t even have to use two hands on him, I’d whoop him all day long. I’m just telling you that Algieri or whoever he was, he couldn’t fight at all," Mayweather Sr. told On The Ropes Boxing Radio.

Besides Algieri, Pacquiao avenged a controversial loss from 2012 by winning a twelve round decision over Tim Bradley in April 2014. Mayweather Sr. shook his head at that victory as well.

"Timothy Bradley ain’t never had no business of beating him in the beginning [of the fight]! It still was a fight, he didn’t knock Timothy Bradley down or anything, where if that boy Timothy Bradley would have fought Shane Mosley or a Cotto [that night], if he’d have fought one of them, he would have got stopped. Timothy Bradley would have [been stopped]," Mayweather Sr. said.
