John Fury has slammed Tyson Fury’s training camp for the showdown with Oleksandr Usyk as a ‘circus’ – and admitted he’s concerned his son will lose the blockbuster fight. 

Fury will go head-to-head with the Ukrainian on February 17 in Saudi Arabia to unify all four WBC, WBA, IBF and WBO belts and crown an undisputed champion.

The big showdown will come from the back of a disappointing display against Francis Ngannou in October, a bout which saw the Gypsy King floored before winning via a split decision.

John Fury has insisted his son is not in decline but admitted he’s concerned Usyk will win if adjustments are not made in camp.

He told Second Out: ‘I never said my son was in decline because he’s not.

‘It’s the people around him who ain’t up to much. His training’s in decline and his camp’s in a bigger decline.

‘It’s not a camp, it’s a circus.’John Fury added” ‘I saw him in the gym in Saudi, watched him spar three or four rounds with a couple of kids – I knew then it was gonna be a hard night’s work.

‘I thought, “What have you been doing?” I was alarmed, I still am.

‘Unless you’re gonna get the eye of the tiger back and go back to the old ways and get the hunger back – sweat, blood, s*** and tears.

‘Because Usyk’s doing that – sweat, blood, s*** and tears.

‘And he’s got disciplined, professional, great people around him, and I don’t think Tyson has that. I really don’t.’

Asked if he’s concerned could suffer his first professional defeat, John Fury said: ‘Absolutely, if he doesn’t make any adjustments, it well could be.’

The winner of February’s bout will become the first undisputed champion in boxing’s blue-riband division in the four-belt era.

Similar to Fury, Usyk goes into the clash with an unbeaten record after a knockout victory against Daniel Dubois in his last bout in August.
