Beterbiev has little experience of fighting men much bigger than him but with his power and skillset he has an excellent chance of KOing Zhang.
I disagree with your words The Chinese octopus should've categorically been DQ'd for spending half the fight holding on like a limpet which he was obviously doing to prevent Beterbiev from landing with scoring shots of his own. Bare minimum the ref should've deducted multiple point from him for it but the fix was in the bag for the home fighter to win and, like I said, they even robbed his opponent in the final.
