Dutchman Verhoeven, 37, boasts an impressive kickboxing resume, reigning as Glory’s heavyweight champion for 11 years and making 13 successful defences, but has boxed just once professionally – in 2014.

But Usyk’s CV in boxing is just as eye-catching – if not more so.

After winning gold at the 2012 Olympics, the Ukrainian has established himself as one of the pound-for-pound greats by achieving undisputed status at cruiserweight and, twice, at heavyweight.

Usyk, 39, has brushed aside Anthony Joshua, Tyson Fury and Daniel Dubois – beating each of the Britons on two occasions – and, despite Verhoeven’s lack of boxing experience, is approaching this bout with the same mentality.

“The opponent might be different but my preparations are not different,” Usyk said.

“I work hard, I do a lot of work in sparring, conditioning and cardio.

“I train like I’m fighting Tyson Fury or Daniel Dubois, because for me it’s a serious fight. It’s not fake. For me it’s not a show, it’s a fight.”

Two big-hitting British heavyweights will collide for a world title in Manchester on Saturday as Fabio Wardley defends his WBO belt against Daniel Dubois.

Unbeaten Wardley, 31, makes the first defence of his title after the Ipswich fighter was upgraded from interim to full world champion last year.

Londoner Dubois, 28, is aiming to bounce back from his defeat by Oleksandr Usyk last summer, as he looks to become a two-time world champion.

With a combined 95% knockout ratio, it seems unlikely the judges will be needed at the Co-op Live Arena.
