According to Floyd Mayweather Jr. (48-0, 26KOs), he finally sat down and had a chance to watch Gennady "GGG" Golovkin (33-0, 30KOs) fight.

Lately, Golovkin has called for a 'dream match' with Mayweather - and GGG is willing to drop down to 154-pounds to make it happen. Mayweather holds the WBC/WBA belts at junior middleweight.

Mayweather was not very impressed with Golovkin's performance against Monroe - and feels very good about his chances to outbox GGG.

Golovkin is not on Mayweather's list of potential opponents for September 12th, when the pound-for-pound iking s scheduled to return to action for the 49th time.

"I finally got a chance to see the guy fight. Congratulations for everything that he's done but even at my weight he can't beat me. I don't knock him. He can't beat me. He can punch, but in his last fight...I don't even know the guy's name, but if I would have worked with the guy - the guy would have beat him. I don't take nothing away from Golovkin. It's obvious that he's done something right. Whoever they put in front of him - he's beat them. He's doing something right thus far," Mayweather said.

"I've seen him fight. Everybody was talking to me about him, so I had to take some time out of my schedule to see this guy. Golovkin goes out and does what he has to do. But at my weight right now, I walk around at 148, 150 - it probably would be a good fight for me, but I'm almost finished [with my career]."
