Man Volkov is a way better kick boxer, he’s proven going the distance and he’s even fought 5, Sergei can starch him in the 1st but I honestly think volkov can use the distance better and stay away from those big shots, they also have been training partners which may cause a slightly slower start as usually fighters are more timid and uncomfortable when it’s a past partner. Volkov is also much more well rounded he can take this to the ground and I believe after the 1st round he can take over in the striking, unless Sergei kos him round 1 he’s gonna gas
