Verhoeven is a huge underdog and victory over Usyk would rank among the biggest shocks in boxing history, arguably surpassing Buster Douglas’ stunning win over Mike Tyson in Tokyo in 1990.

The Dutchman won 66 of his 76 kickboxing fights and has not lost in more than 4,000 days. But the 37-year-old has had only one professional boxing bout – a stoppage win over a journeyman 12 years ago.

Usyk, meanwhile, is one of boxing’s most decorated fighters; an Olympic gold medallist, undisputed cruiserweight champion and two-time undisputed heavyweight champion who remains unbeaten in 24 professional bouts.

The 39-year-old wore a striking Egyptian-inspired white and gold outfit, complete with a cape and draped sleeves, though his answers did not match the extravagance of his attire. At one stage, he even appeared to be on a video call during the media-only event.

When it was put to him that Verhoeven believes his lack of experience could bring an element of surprise Usyk has never faced before, the champion replied: “I have no idea how many rounds this will go. I’m not sad with 12 rounds. It’s normal. But I don’t know. When I have the chance, I’ll do it.”

The contest will count as a defence of Usyk’s WBA ‘Super’ title and he would also lose his IBF belt if defeated, although Verhoeven is not eligible to win either championship.
