Floyd Mayweather Sr., father and trainer of Floyd Mayweather Jr. (49-0, 26KOs), has no trouble admitting that IBF/IBO/WBC/WBA middleweight champion Gennady Golovkin (36-0, 33KOs) would be too big and too strong for his son.

Mayweather retired from boxing last year, after dominating Andre Berto for twelve rounds at the MGM Grand in Las Vegas.

After capturing world titles in five weight divisions, from 130 to 154, everyone always wondering if he would chase that sixth title at the middleweight limit - but Mayweather had little to no interest in climbing beyond the junior middleweight limit.

Golovkin has always called Mayweather his 'dream fight.' Mayweather is the only opponent that Golovkin would consider facing at a lower weight. Golovkin had often called for a fight with Mayweather and he was willing to squeeze down to 154 to get a deal done or even 155 so the middleweight belts could be at stake.

Last month, IBF welterweight champion Kell Brook moved up by thirteen pounds to face Golovkin at the middleweight limit of 160. While Brook started off very well in the fight, Golovkin's size and power was eventually too much. He was able to absorb Brook's best punches and continued to come forward. The fight was stopped in fifth round as Brook had suffered a fractured orbital bone and GGG was starting to dominate.

"Kell Brook was probably beating him and stuff but, at the end of the day, even with Floyd, the guy is too big, he can take your punch, you can’t take his punch. He can take your punch, but you really cant take his punch and he can take what you give him but you ain’t gonna be able to take what he gives, and plus he can smother you too. I’m just telling you that it’s not a good break for my son," Mayweather Sr. told On The Ropes Boxing Radio.

"You know, I don’t doubt my son on nothing he can do. Kell Brook did it, you see what happened though, he got hit and his eyes closed and he couldn’t see nothing. I’m just telling you that those kind of things can happen. They can happen and they will happen, so I wouldn’t even suggest that. Let him go fight somebody his own size."
