"In comparison with war, boxing is child's play."

Those were the words uttered by Oleksandr Usyk in April after he left Ukraine's front line to prepare for the rematch against Anthony Joshua, which takes place in Saudi Arabia on Sunday.

Eleven months ago, Usyk placed himself on top of the boxing world with a stunning victory over Joshua at the Tottenham Hotspur stadium – where he dominated what was only his third fight at heavyweight level.

The aftermath saw talk of a unification bout against Tyson Fury, while questions were also raised as to whether Joshua would walk away, but both of those discussions were irrelevant in the grand scheme of things.

In February, Russia stunned the world with the invasion of Ukraine and citizens took to the frontline to defend their nation, with Usyk travelling back to Kiev to fight.

Boxing, understandably, was far from the mind of Usyk, who told CNN: "I really don't know when I'm going to be stepping back in the ring. My country and my honour are more important to me than a championship belt."

Usyk will this weekend put his WBO, WBA Super, and IBF titles on the line against Joshua and shoulder the hopes of a nation who have had to cope with unthinkable trauma.

Sport, in situations like this, is largely irrelevant and few would criticise Usyk if he were to struggle in his rematch given the experiences he has endured – but he may find extra encouragement from Joshua's comments ahead of the bout.

Speaking to the Daily Mail, Joshua described the months since he lost his belts to Usyk in north London as a "nightmare", words that may sting Usyk's camp given what has transpired away from the ring.

Many would suggest Usyk, having been the underdog in the initial bout and still with limited heavyweight experience, has nothing to lose – but he would be the first to argue that is not the case.

In terms of preparation, Usyk, like Joshua, has made significant adjustments and, having been at the lower-end of the heavyweight scale for the first clash has bulked up for the rematch, while the Brit has done the opposite.

Joshua had the weight, height and reach advantage for the first bout but did not put it into effect, with it clear after the opening five rounds that he was on the back foot and his best chance of winning was a knockout – but he never pushed for a stoppage.

Usyk, now displaying added bulk, may look to be more aggressive and to take the sort of chances that Joshua passed up back in September, though that is an approach he has not shown yet in the heavyweight division.

The champion's past two bouts have gone the distance and he earned unanimous decisions but, in the heavyweight game, it is a brave approach to look to stand firm, as just a single punch can change the picture entirely.

With additional weight behind him, Usyk should be able to hit Joshua harder this time around, but the full force of his strikes may well come from a different source – the support of his nation.

Promoter Alex Krassyuk told Sky Sports that Usyk travelled across Ukraine to visit high-ranking army officials, fans and injured combatants while supporting the resistance of the Russian invasion, where he received significant support and backing to return to the ring for the rematch.

"People want him to fight. People want him to win. They all want the Ukrainian flag to be risen and the Ukrainian anthem to be heard throughout the planet," he said.

That level of support can inspire Usyk when he faces a rejuvenated Joshua.

Oleksandr Usyk has claimed "expectations are not met every time" after the Ukrainian surprisingly came in light at his pre-fight weigh in ahead of the rematch with Anthony Joshua.

The heavyweight champion was widely reported to have been bulking ahead of going toe-to-toe with Joshua in Saudi Arabia but, clocking in at 15 stone and 11 pounds, was only marginally heavier than his weight in north London last year.

Usyk, always keeping his cards close to his chest, refused to confirm whether it was a ploy for people to think he would be showing a heavier weight for Sunday's bout and was not drawn into pre-fight verbal jabs when interviewed after the scales.

Joshua also downplayed the significance of the weigh-on and face-off, having clocked in four and a half pounds heavier than last September, and remains focused on getting it done in the ring.

"For me, personally, the face-off doesn't mean anything. It's about throwing leather, the face off doesn't win fights. All of this stuff, weight, none of it matters to me, I'm just looking forward to the fight," he said.

The Brit has been preparing for the fight to go the full distance, just as it did at the Tottenham Hotspur Stadium when he lost his belts, adding: "I'm 100 per cent ready for 12 rounds and anything less than that is a bonus."

At 32 years old, Anthony Joshua should be enjoying the prime of his career, but in his rematch against Oleksandr Usyk on August 20 he faces the prospect of his status as a truly top-echelon attraction coming to an end.

Joshua, an Olympic gold medallist and maybe the most physically imposing heavyweight in boxing, will contest his 12th consecutive world title fight when he steps into the ring in Jeddah, Saudi Arabia, with nine wins and two losses over that span.

The Watford-born star has lost before – in a shocking upset via seventh-round knockout against Mexico's Andy Ruiz Jr at Madison Square Garden – which he proceeded to avenge in style, with a dominant unanimous decision victory in the rematch, also in Saudi Arabia.

He will be hoping the story repeats itself after his convincing defeat at the hands of Usyk at Tottenham Hotspur Stadium in September, as he again prepares for his rematch on the other side of the world, away from all the distractions of friends, family and the celebrity that comes with being the heavyweight champion of the world.

But Usyk is a very different proposition than Ruiz ever was.

Ruiz was a late replacement opponent when he faced Joshua, and it was clear the towering, muscle-bound Brit underestimated the stout, stocky Mexican, as he was shocked early by the challenger's power and never truly recovered.

With a full camp and a renewed sense of focus, Joshua picked apart Ruiz in the rematch, with the fight leaving even the most passionate Ruiz fans questioning how he ever pulled off the upset in the first place.

Usyk, on the other hand, is no late replacement for anyone, and he has been on the same path towards the heavyweight throne as Joshua since their amateur days. At the London 2012 Olympics, where Joshua collected the super-heavyweight gold medal, Usyk ran through the heavyweight division, and has since put together a perfect record in the cruiserweight weight class.

After building a record of 16-0, including going 7-0 in cruiserweight world title fights, Usyk made the decision to make the jump up to heavyweight, and after wins against Chazz Witherspoon and Derek Chisora, he earned his shot against Joshua, and took it with both hands.

For Joshua, this time there was no lack of planning, and there was no reason to underestimate Usyk's world-class ability – in other words, there were no excuses. So how can he make sure the rematch is nothing like the original, and become a three-time world champion in the process?

Usyk is a near-perfect heavyweight fighter, with power in his hands to sting anyone, while retaining the foot speed and agility of a much smaller cruiserweight – but like every boxer, he has flaws, and tendencies that can be exploited.

Without a doubt, Usyk fights best as the aggressor, taking the centre of the ring and marching forward to force his opponents to fight with their back near the ropes and nowhere to run.

But Joshua is the bigger (six-foot-six against six-foot-three), longer (82 inch reach against 78 inch reach) and younger (32 against 35) fighter, meaning he has the physical tools necessary to deny Usyk his desired position as the ring general dictating the pressure.

Also, in Usyk's two most competitive world title fights – a majority decision win against Mairis Briedis and a unanimous decision against Murat Gassiev – he showed his defence is far from impenetrable, particularly against left hooks and body shots. The left hook in particular, including feints, seem to draw out the biggest reaction from Usyk, who usually opts to retreat and reset as opposed to firing back a counter.

He is also far from a quick-starter, instead opting to remain relatively cautious through the opening few rounds as he measures his distance and timing, before increasing his pace and volume in the second half of the fight to overwhelm his tiring opponents.

If Joshua is able to hold the centre of the ring early, rely on his length advantage to keep Usyk on the outside, and make a concerted effort to focus on body shots whenever the Ukrainian closes the distance, he could find himself with a healthy early advantage and the momentum heading into the middle stages of the fight.

Identify what went wrong in the first fight

Both Gassiev and Briedis fought in an orthodox stance, just as Joshua does, while Usyk fights out of the southpaw stance – meaning Joshua will have his left foot forward, and Usyk will have his right foot forward.

In orthodox versus southpaw matchups, the fight is often decided by the footwork battle, and Usyk dominated in that department for all 12 rounds in his first look at Joshua.

Whoever controls the 'outside' foot position is able to fire straight shots to the body and head with their rear hand, while also being able to easily circle away from their opponent's straight shots as they try to punch across their body diagonally.

While Usyk has the advantage as far as foot speed goes, the problem in the first fight was more about Joshua's willingness to concede the positioning battle and try to punch his way out of it, which led to plenty of flailing swings and a lack of clean connection.

One way to dissuade the southpaw from taking the preferred position is to aggressively use the left hook early – to the head, as Joshua loves to do, but more so the body – as it will come from the direction Usyk is constantly trying to move, lean and escape to, while his southpaw stance naturally exposes the vulnerable liver area.

If Usyk begins to feel like that left hook is coming every time he moves towards it – or absorbs an uncomfortable blow to the liver – he could be more willing to hold a neutral stance and level the playing field, completely changing the dynamic from their first meeting and opening the door for Joshua's power and size advantage to come to the fore.

Promoter Bob Arum is "confident" Tyson Fury will come out of retirement to face the winner of Saturday's heavyweight title rematch between Oleksandr Usyk and Anthony Joshua.

Fury retained his WBC world title with a victory over Dillian Whyte at Wembley in April and stated that was his last fight. 

The Brit appeared to backtrack this month by stating he would be returning to the ring and wanted to face Dereck Chisora for a third time, having already been victorious over his compatriot in 2011 and 2014.

Fury then announced once again that he has retired in a social media post on his 34th birthday last week.

Joshua and Usyk will do battle once more this weekend in Saudi Arabia, after the former undisputed cruiserweight champion took the Brit's IBF, WBA and WBO belts with a unanimous decision victory at Tottenham Hotspur Stadium last September.

Arum believes the 'Gypsy King' can be tempted back into the ring to face whoever comes out on top.

He told Sky Sports: "Absolutely - it's really the only fight that makes sense for Tyson Fury.

"I've discussed this with my co-promoter of Fury, Frank Warren, and once this fight is over we're going to put together a total unification match between the winner and Tyson Fury.

"Now, if Usyk wins the fight, which I expect, that will be quite easy to do because we're very close to the Usyk people as they're the same people who manage Vasyl Lomachenko who fights for us. If Joshua wins, Eddie Hearn is his promoter. We've talked many times with Hearn about various matches and I'm sure we'll be able to come together on this one.

 "I've talked with him [Fury] and every day is different, but he's a fighter and if the right fight is there then Fury will be up for that fight. The right fight is the unification fight against the winner of Usyk and Joshua and I think - based on my conversations with Fury - he'll be up for that challenge.

"How much longer he will go after that, god only knows and I'm not sure, but I'm confident at least that he'll answer the bell for that major fight."
