A good challenge to him now, preparing for his upcoming fight, a new division which would be the first step in his new journey.
The first step and his possible first win, well, there should be no problem with him in this fight, it's on the division that he is comfortable, there is no more weight issues for sure and we will again see Casimero winning via KO. There's a reason why he is the heavy favorite here, that's because people still believe that he still is a champion.
