MGM Grand, Las Vegas - WBC/WBA/WBO welterweight champion Floyd Mayweather Jr. (48-0, 26KOs) has once again touched on the subject of a possible fight with IBO/WBA middleweight champion Gennady "GGG" Golovkin (33-0, 30KOs).

Golovkin has stated in several interviews that he's willing to drop down to the junior middleweight division for a fight with Mayweather, who plans to return on September 12th at the MGM Grand.

Mayweather has already ruled out a fight with Golovkin, but feels he's too smart for him.

"Even with me being at my weight, I'm just too smart. You have guys out there who can punch with both hands, that go to the body good. The thing is this, I do everything good. But my best attribute is that I'm very, very smart. He's a solid puncher, but he's straigh up and down...really no special effects, at least not to me. You could see him coming straight ahead," Mayweather said.
