Roger Mayweather, uncle and co-trainer of Floyd Mayweather Jr., wants his nephew to have a rematch with Manny Pacquiao.

Mayweather won a twelve round unanimous decision over Pacquiao on May 2nd at the MGM Grand in Las Vegas. After the contest took place, Pacquiao revealed that he further aggravated a pre-existing right shoulder injury during the fight.

Pacquiao says the injury affected his overall performance. But even with a healthy shoulder, Roger says the end result would have been the same.

"Whatever he do, I don’t think that [shoulder injury] made a difference. I don’t think that made a difference because the thing of it was, my nephew was on top of him and he couldn’t really do anything as far as keeping Floyd off of him. That’s how it was," Roger told On The Ropes Boxing Radio.

Roger claims his nephew's performance was affected by two injured hands. He says Floyd's hands were bothering him during training camp. Roger predicts a knockout victory if they ever have a rematch.

"I think it was one sided but I think they should have a rematch. Why I say that is because if Floyd fought Pacquiao with good mother***ing hands, he would stop Pacquiao, period. He would stop Pacquiao. I did say that Pacquiao fought a good fight but I also know that Floyd’s hands were hurting because I train Floyd, but it is what it is," Roger said.
