I guess this is a dangerous fighter for Golovkin indeed, After Drawing in his first fight with Canelo Alvarez and losing the second one I really think that he will have a very hard time with Derevyanchenko, Talk about getting bias here but that is how I see things and Derevyanchenko is durable in the ring he doesn't have blazing speed but he is not slow either.
Derevyenchenko got a formidable power but not that formidable and he is a guy that is not easy to be hit, I guess Golovkin is not so motivated in this fight not like what he has between a Canelo Alvarez fight, We might say that he is not motivational to win this so I guess we can see a Derevyanchenko win it might be a Unanimous Decision regarding the performance Derevyanchenko could give.
I checked Dereyvanchenko and I'm not impressed at all then I checked both of their fights against Jacobs and it seems Golovkin has the upper hand, about motivation I don't think so his motivation should be high he is coming from a lost and he needs to regain that belt again if he loses here, that's two in a row and might as well retire Golovkin is a fighter and he will do everything to win here.
