I don’t think this fight will be all that competitive as Golovkin looks to be in the best shape of his career and is a world class fighter while Szeremeta is European level at best.
Szeremeta isn’t a bad fighter he just isn’t on the level of Golovkin and from watching his fights there’s nothing to suggest he can beat him. His hands are often low and he doesn’t have a lot of power either.
I think Golovkin will look like he used to and KO Szeremeta in 7 or 8 rounds before moving onto a bigger fight.
