It will not be a surprise if Haney will win again, the one that should work harder here is Kambosos because his career is just starting to get better but if he lose again, he might have to start over again, which for some boxers it will lead to early retirement.
Many people rely on Haney abilities because he is superior to Kambosos, but within 5 months of the previous boxing fight then Kambosos will train hard to improve his abilities for the second fight, maybe his coach has reviewed some records in the previous fight so Kambosos should level up. I think Kambosos is still young so even though he lost for the second time then his boxing career is still long and he has had valuable experience to become a professional boxing career.
