They will surely aim for another rematch because it can easily attract viewers and bettors. We all know that boxing fans always want to know who is the best among the best. It will also be another opportunity for Bivol but if ever he'll faces Canelo, he must have enough time to prepare because for sure, Canelo would aim for a sure victory this time.
I think the way Bivol can prove he's better than Canelo is really a strong fighter mental since not every boxers can perform as good as they can when the crowd favoring on their opponent side. If the rematch happen and Bivol still win again, I have no word to say since I believe many people will disappointed to see Canelo still not able proving he's deserve to be on light heavyweight division. It just end of Canelo era since he have beat the best boxer on his current weight, but he's bad on the next weight.
There's no discussion anymore about Bivol and Alvarez once he beat him again in their possible rematch, though we are all witness of the dominance of Alvarez in his current weight but going up to another division is not for him or he needs to take an extra step before dethroning Bivol from his current thrown.
Though Zurdo is also aiming for Bivol's belt and he also has that same intention to move up and be a champion.
It's Bivol's weight division, and he has that advantage. We saw his greatness against Alvarez, and if he continues to dominate, it will be good for his career, it will bring him more money fights.
