Floyd Mayweather Snr believes his son should avoid a rematch with Marcos Madiana, insisting Amir Khan would have been his preferred choice because he is the "easy one in the bunch."
Last week in an interview with Laten media Mayweather Jr revealed he will meet Maidana in a rematch of the May showdown this September, with the Argentine later confirming through his Twitter account that talks were ongoing.
While the five weight world champion recorded his 46th career victory in their last meeting, Maidana provided the 37-year-old with his sternest test in the ring in years before eventually succumbing to defeat on a majority decision.
Although both fighters appear keen on the proposed rematch on 13 September, Mayweather's trainer is not on board with the plan.
"They say he's gonna fight Maidana again," Mayweather Snr said in an interview with On The Ropes Boxing. "If that's the case, he might be putting Maidana over, we'll see about that though. I wouldn't like to see him fight Maidana – not that he can't beat Maidana, but Maidana does too much dirty s**t and his corner is dirty.
"His corner told him to do this s**t, they told him, 'hey fight dirty, so whatever it takes to win.' That's what they said, those were their words. I'm just saying, he's not even worth fighting to be honest."
Khan had been in the running to attempt to dethrone Mayweather in May but he was eventually overlooked in favour of Madiana and settled for a place on the undercard against Luis Collazo.
Although the Brit's Ramadan commitments effectively ruled him out of Mayweather's September slot, Mayweather Snr believes a fight with Khan would have been the best option for his son.
"If I was little Floyd, if I was Floyd myself, I would take me the easy one in the bunch. Amir Khan is a good fight for him but I'm just saying that we're going to wait and see. Amir Khan ain't got no f*****g jaw, he ain't got no chin. If he gets hit he's gone, especially if he gets hit right he's gone."
Mayweather Snr was also quizzed on the possibility of a long-awaited showdown with Manny Pacquiao. Despite the unbeaten American's refusal to do business with Pacquiao's promoter Top Rank CEO Bob Arum, Mayweather Snr did little to quell talk of a possible meeting, but doesn't believe a contest would be the competitive spectacle many boxing fans have yearned for.
"We'll I'm gonna tell you this right here, it could be closer than you think," he added. "I think for me, little Floyd would box his ass out. I'm just being honest. It could be for a million different reasons why that fight is not taking place. "
