LONDON, England -- Daniel Dubois was adamant that he'd write his own script and be crowned Britain's first undisputed heavyweight champion since Lennox Lewis in 1999 at Wembley Stadium this weekend.

Egis Klimas, Oleksandr Usyk's manager, has heard all the noise before.

After engaging in an uncomfortable war of words with two-time former champion Tyson Fury and the 36-year-old's camp during their two-fight series last year, the 60-year-old dismissed suggestions that Britain would belatedly be brimming with pride on Saturday.

Instead, he believes - as many neutrals do - Ring and unified champion Usyk (23-0, 14 KOs) will record another repeat victory over British opposition in dismantling IBF titleholder Dubois, a month shy of two years after their first meeting in Wroclaw, Poland.

"We're back again here in London. Look, he [Usyk] did it once and will do it again, we're very confident as a team. It's the same guy, what could have changed in a couple of years? You cannot train your mind, his weakness is this," he said at Thursday's press conference.

That was in direct response to Queensberry chief Frank Warren declaring Dubois (22-2, 21 KOs) was coming into his prime. While overplayed perhaps, it's not an overstatement.

Jarrell Miller and Filip Hrgovic were genuine 50-50 fights against unbeaten opposition, while two-time unified titleholder Anthony Joshua - a figurehead for British boxing - was expected to teach this young man a lesson but found himself quickly and emphatically overwhelmed.

"Look at his resume, he has the experience, a great team behind him, they [Dubois and Usyk] have shared the ring, he knows he can hurt Oleksandr and has done before, beaten world-class fighters, I think he's gonna do it, I really do," Warren stressed.

"He's different than those three fighters and history will be made on Saturday night, you'll see," Klimas replied, before Usyk repeated 'don't push the horses' - an ill-translated reference to an over-inflated sense of self by the boisterous Brit's team.

Dubois is entering this encounter in-form and motivated to do what no man has - Mairis Briedis got closest - though he will not have boxed for ten months by the time the first bell rings this weekend. No injury and one untimely fight week illness aside, that's not exactly an encouraging sign for someone supposedly in the midst of their fighting prime, is it?

Joseph Parker, his original opponent on February 22, was naturally among the interested audience Thursday and reaffirmed his preference to face Usyk next, if he could choose in an ideal world. The affable Kiwi (36-3, 24 KOs) exemplifies the benefit of meaningful activity and no-one could've predicted he'd be the centre of media attention here after a forgettable 10-round points win over Jack Massey two-and-a-half years ago.

A month earlier, his conqueror Joe Joyce and Usyk were both ringside watching Fury-Derek Chisora trilogy no-one wanted nor asked for, with Fury later declaring Joyce was the division's boogeyman and Usyk - four months removed from unseating Joshua - would have to do more than beat 'a bodybuilder' to justify an opportunity at The Gypsy King. Time flies.

We're not living in an ideal world, otherwise Dubois-Parker would've been rescheduled at the earliest convenience to settle the No. 1 contender spot. The 33-year-old wouldn't have then felt compelled into politely staking his claim for an Usyk opportunity at a bare-knuckle event in Italy, unknowingly a day before Usyk-Dubois 2 was officially announced on April 27.

Dubois' head coach Don Charles insisted the time for talking was over and he wouldn't say much, but even he had enough left in the tank to fire back a reply.

"He must have been sleeping for the last three fights Daniel has had. Can somebody please wake him up?"

Klimas offered the perfect rebuttal. "While I was sleeping Oleksandr beat, two times, Tyson Fury." 

Usyk's longtime friend and sporting director Sergey Lapin shrugged his shoulders and called it an illusion when asked to assess Dubois' development since their first fight given the improved resume since.

Much to the frustration of Dubois' manager Riz Khan - subtle mind games at play again - Saturday night will answer more pressing questions atop the sport's glamour division, where all it takes is one punch.

Usyk, ever successful across England dating back to 2008 at the European Championships in Liverpool, had dreams of walking out at Wembley as a professional footballer.

Instead, he'll make his first outing beneath the arch of the National Stadium seeking to become a three-time, two-division undisputed king against Britain's Dubois, 11 years his junior, as their heavyweight rematch will headline a DAZN PPV (£24.99) that gets underway from 5.30pm BST and 12.30pm ET.
