Anthony Joshua's fans fear that a larger Usyk could cause more problems
AJ must regain his belts, especially after he lost the London bout last year.
Joshua has been hard at work in preparation for this epic fight.
The winner could face Tyson Fury, who would unify the division if the Gypsy King retires.
However, AJ is aware that Usyk will face a difficult and long battle.
Despite his small stature, the Ukrainian fighter was more classy in the first match.
New footage from training shows Usyk gaining more muscle to enhance his punches.
It appears that the ace has also maintained his lightning speed and quick feet.
Fans believe that Usyk's larger frame and bulk could make it difficult for AJ to handle him again.
