Moses Itauma will encounter what many expect to be the toughest test of his career so far in Dillian Whyte on Saturday night in Riyadh, Saudi Arabia.

The 20-year-old has yet to put a foot wrong over the course of 12 fights to date but Whyte, a former world heavyweight title challenger, has seen it all during his 34 outings as a pro.

They have 43 victories between them in the paid ranks, but which of them are the most significant? We take a look at both of their top-five wins ahead of Saturday night’s Esports World Cup main event, which is available live on DAZN pay-per-view.

The Australian McKean, whose only previous loss was a knockout against contender Filip Hrgovic, was supposed to provide something of a test for Itauma. But the Chatham-born puncher swept his fellow southpaw aside in just 117 seconds with two knockdowns from perfectly timed left-hand counters.

Like McKean, former American footballer Balogun had only lost once before he crossed paths with Itauma. But just like the big Australian, it was all over very quickly. Balogun had actually shown tremendous heart to make it out of a first round, in which he was dropped early. But he survived for only 46 seconds of the second round as Itauma put him down twice more in showreel fashion to clinch victory.

Whenever a young heavyweight prospect needs rounds, one of the first men to receive a phone call is the usually durable Mariusz Wach. In recent years the Pole has gone the distance with Frazer Clarke, Kevin Lerena, Hughie Fury and Dillian Whyte. However, Itauma was in no mood to join that list. He attacked Wach from the outset, peppering his head and body and eventually forcing a stoppage after 2:30 of the second.

This was the first fight of Itauma’s career scheduled for 10 rounds, but he marked it by seeing off the 25-3 Kazakhstan-born German early in the second. Itauma spent the first three minutes softening up his opponent before finding a finish 50 seconds after the restart. It was a rapid-fire hook-cross-hook combination that ended the fight and further cemented itauma’s position as the world's most promising heavyweight prospect.

Itauma illuminated what was his Saudi Arabia debut by crushing the 10-1 Bernath in just 113 seconds. Itauma had a chat with Mike Tyson during fight week and it was a performance that the heavyweight legend would have been proud of as the teenager dropped Bernath with a heavy jab first and then forced the stoppage once the big Hungarian had managed to get to his feet.

Following their disputed Manchester epic in December 2016, the British heavyweights finally clashed for the second time two years later. And, after Whyte won a close split decision the first time around, he refused to leave it up to the judges in this rematch. He was behind on two of the cards after 10 rounds but with a minute left of the 11th, he ended this classic with a stunning left-hook KO.

Given how Joseph Parker’s career has gone since that night in London back in the summer of 2018, this is a Whyte victory which has aged like a fine wine. Parker, who had only lost to Anthony Joshua at this point, was down in the second and the ninth, and, despite dropping Whyte himself in the 12th, the hometown favourite clinched a unanimous decision victory.

Having lost by violent KO at the hands of Povetkin seven months earlier, Whyte went to Gibraltar on a revenge mission with his career in the balance. A second defeat for the Bodysnatcher would have been disastrous, but he dismantled Povetkin inside four one-sided rounds to reclaim the WBC interim title. His reward for the victory was a shot at WBC heavyweight champion Tyson Fury at Wembley Stadium in April 2022.

Browne was 25-0 when he arrived in London for this fight with Whyte. But, after a bitter build-up, the Aussie suffered a career-first defeat when Whyte scored another knockout by virtue of his trademark left hook, leaving Browne out cold early in the sixth round.

Chisora had sent a table flying at the final press conference ahead of this bad-tempered affair a fortnight before Christmas in 2016. But it was Whyte who did just enough across this all-British thriller to edge a split decision.

Steve Gray had Chisora a 115-114 winner, but Michael Alexander (115-114) and Howard Foster (115-113) both scored it narrowly in Whyte’s favour to hand him the victory.
