Middleweight mauler Jermall Charlo says the big fight he wants next is Canelo Alvarez ... because when it comes down to it Canelo is bigger and better than Gennady Golovkin.
Most agree that Jermall is on the cusp of superstardom ... but he needs one huge fight to catapult him from a boxing star, to a household name.
A win over GGG or Canelo would probably do the trick ... but when we talked to JC in NYC, he said he wants one guy -- the better guy -- much more than the other.
