Floyd Mayweather has just been called out by the most dangerous boxer in the world ... Gennady Golovkin ... who says he's 100% confident he would crush Money ... if they ever got in the ring.
Triple G appeared on "TMZ Hollywood Sports" and told us a bout with Mayweather would be his "dream fight" -- if Floyd ever agreed to come up in weight and fight the 33-year-old phenom.
FYI -- Triple G is a BEAST in the ring ... having K.O.'d his last 20 opponents in a row!!!
There's more ... we also asked Golovkin about fighting Oscar De La Hoya, who recently told us he'd want to get in the ring with Triple G if he ever comes out of retirement.
Long story short ... if Oscar's serious, Golovkin says he's absolutely ready to rumble.
Floyd Mayweather is already trading shots with Gennady Golovkin ... telling TMZ Sports the guy's just running his mouth for a payday -- and he's way out of his league.
Golovkin -- who's knocked out his last 20 opponents -- told us Mayweather would be his "dream fight" and is 100% certain he'd win if they ever got in the ring together.
Now, Mayweather's camp is issuing a response ... saying, "Everyone in boxing wants to fight Floyd. It's the biggest payday they could possibly have."
"[Golovkin] has never fought a top opponent in his whole career ... we're surprised you guys would even have him on your show to be honest."
Sounds like fightin' words.
