Picture of Tyson Fury's physique emerges ahead of Oleksandr Usyk bout and fans think the fight is already done

A picture of Tyson Fury's physique has emerged online ahead of his undisputed clash against Oleksandr Usyk, and fans think the fight is already done.

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

Anthony Joshua, who could fight the winner down the line, has given his prediction for the monstrous contest.

Fury, meanwhile, has arrived in Saudi Arabia without a key family member in his team.

Ahead of facing the undefeated Ukrainian, the self-proclaimed 'Gypsy King' has shown off his remarkable condition in a new post on social media.

He shared a topless picture of himself on Instagram, accompanied with the caption: "Undisputed incoming."

The image left fight fans online stunned as they believe he will do the business against Usyk.

One X user wrote: "Yeah he's been working for this one."

A second tweeted: "He looks great. Usyk is in trouble."

A third added: "Fury is going to be the first man to stop Usyk."

A fourth commented: "We could be about to see the very best of Fury."

A fifth predicted: "Tyson in 8," while another said: "Looks like he actually bothered training for this fight then."

Fury has been consuming up to 6000 calories every day during his training camp, with a protein-packed diet consisting of chicken and eggs to boost his athletic performance.

He appears to be in the best shape of his career as he looks to bag all the world titles in the heavyweight division.

The 35-year-old hasn't fought since his controversial victory over former UFC champion Francis Ngannou last October.

As for Usyk, he hasn't fought since his TKO victory over Daniel Dubois last August.

Fury and Usyk were supposed to fight on February 17 until the superstar Brit suffered a nasty cut in sparring.

But their rearranged showdown is just over a week away as an undisputed champion will be crowned in the Middle East.
