Tyson Fury and Oleksandr Usyk clash next month for undisputed glory.

Tyson Fury vs. Oleksandr Usyk has been tipped to ‘end in controversy’, according to a former world champion boxer.

Fury will defend his WBC belt as Usyk will put his WBA (super), IBF and WBO world titles on the line when they meet on May 18.

The Saudi Arabia showdown will crown an undisputed champion at heavyweight as Anthony Joshua, who could fight the winner, has made his prediction.

Johnny Nelson, who like Usyk held the WBO cruiserweight title during his career, has also given his prediction for the monstrous battle.

And he’s backed Fury vs. Usyk to ‘end in controversy’ after having a dream about next month’s undisputed clash.

“I had a dream and Tyson Fury was in this dream. I’m trying to understand what I saw. It was controversial and Tyson Fury was not happy,” he revealed.

“I don’t know if that meant Tyson Fury won controversially or Tyson lost controversially, but I know there is a controversial decision with this fight.

“Mark that down! Tyson was pi**sed off, I don’t know if he lost or won controversially. But there is going to be controversy!”

Nelson believes both Fury and Usyk can win by knockout as he highlighted the Brit’s height.

He also believes the self-proclaimed ‘Gypsy King’ could walk away from boxing if he loses to the Ukrainian.

“I think both men can win by knockout, without a doubt,” he added.

“Each heavyweight fight Usyk is having he’s getting more comfortable being in there with heavyweights.

“I know he had five heavyweight sparring partners, I spoke to three of them, and they said he got stronger as the rounds went on, and he manhandled all five of them.

“We’re thinking that Fury’s physicality is going to be a big problem for Usyk.

“But Tyson Fury’s physicality is his height, reach and speed, not the power. Speed leads to power – and both fighters can get knocked out.

“If Fury gets knocked out like Francis Ngannou did, he’ll chuck it in.

“His pride as a fighting man will make him internally combust, doesn’t matter what his PR people say, if that happens to him he’ll struggle to accept it.

“He said before he’d struggle to accept losing to a little cruiserweight.”
