Who wins? Tough call. Bivol is a great mover. But Gvozdyk is a long, skilled boxer puncher. A bigger and stronger LHW.
Really great match up and such an intriguing one. Both highly skilled excellent boxers. Even if you favour Bivol this would be the only fight of his to date he wouldn't have won via schooling or wide. It would be a very close and evenly contested affair and one either are capable of winning.
Prime Gvozdyk? Most people on this board had him being the future of the LHW division. Don't let that Beterbiev fight fool you, prime Gvozdyk definitely beats Bivol.
If Beterbiev knocks out Bivol many people's opinions on the outcome of this will shift drastically. They do share a common opponent in Chilemba. Gvozdyk stopped him on an injury and Bivol outpointed him so you can't really read too much into it
