This is a solid second fight for Gassiev at heavyweight as Wallisch is a fringe European level fighter and has fought quite a few notable heavyweights though has lost to most of them. Murat Gassiev is a former unified world champion at Cruiserweight and after an inactive two years is finally getting back into the sport. Wallisch is 35 and doesn’t have good punch resistance or great skills honestly. I don’t think he can punch as hard as Gassiev can either even though hes the more natural heavyweight.
I think Murat Gassiev will win by knockout within six rounds due to being more powerful and his good body punching.
