THE SUPERFIGHT WILL HAPPEN ... because Canelo Alvarez says he WILL fight Gennady Golovkin -- telling TMZ Sports, "It's gonna happen very soon."
Canelo is currently in Dallas gearing up for this weekend's big fight against Liam Smith -- the undefeated WBO light middleweight champion. If he can emerge victorious, GGG will be waiting on the other end.
"There's no doubt about it that fight's gonna happen," Alvarez told us through a translator.
Some critics -- and even other boxers -- have accused Canelo of "ducking" Golovkin.
