Eddie Hearn believes Dillian Whyte "is a live dog" in the heavyweight match-up with Tyson Fury, as we await confirmation of the domestic bout.
Hearn, who has said he has a "back seat" after losing the purse bid for the fight, thinks Whyte can cause WBC world champion Fury some problems.
The Matchroom promoter believes much will come down to Fury's "hunger" and how much he wants to defend his title.
Fury (31-0-1, 22 KOs) was last in action in October 2021 after defending his crown in Las Vegas in an epic win over rival Deontay Wilder.
Whyte (28-2-0, 19 KOs) is back in action for the first time since overcoming Alexander Povetkin of Russia in a rematch in March of last year. But he has waited for years for his shot at a world title fight.
The Brixton fighter spent over 1,000 days as the WBC's No 1 ranked contender before he was brutally knocked out by Povetkin in August 2020.
But he looks likely to finally get his shot at the big time with the fight pencilled in for April 23 at either Wembley or the Principality Stadium, Cardiff.
He told talkSPORT: "He's a tremendous puncher, a big strong, rugged heavyweight. Tyson Fury, coming off the Wilder fight, he was down twice in that fight.
"Wilder is a big puncher of course and Fury, at the moment on paper, is the best heavyweight in the world, but Dillian Whyte can beat all the heavyweights on his night.
"He has the equaliser as he's a tremendous body puncher, a left hook that can turn your lights out as well.
"Fury is the favourite going into the fight, but Dillian Whyte is a live dog in that fight and a lot of it comes down to Tyson Fury's hunger.
Hungry on Instagram
"He's very hungry on Instagram, but when he comes down to it - how much do you want it?
"Dillian wants it bad, so I think he's got a great chance."
Frank Warren and Queensberry Promotions won the virtually held purse bid with an offer of £30.6m; Hearn's bid was £23.9m.
Warren says Hearn "held the record for putting in the highest ever purse bid… for 10 seconds" before his team's offer of almost £7m more emerged.
The deal though has yet to be drawn up between Fury and Whyte with the latter unhappy with the 80/20 purse split demanded by the WBC.
"The winner has seven or ten days to pay the deposit and then they have 14 days to confirm the date and the venue," Hearn told IFL TV.
Queensberry's Promotions, who will promote the fight alongside Top Rank, have already paid the £4.1m deposit. But a date and venue have yet to be announced with Hearn claiming the contracts need to be signed by February 21.
"We've just got some contracts this weekend," Hearn added. "I'm with Dillian's team tomorrow [Tuesday] to have a chat through it.
"Back seat for me in that one. My old pal Tyson Fury, I'll let him have the limelight on that one.
"It's a good fight and hopefully it all gets made.
"There was a lot of talk for a long time about step asides and all this, but in the end what is happening is what we thought would happen, which is Tyson Fury against Dillian Whyte and AJ vs Usyk.
"Two good heavyweight fights and hopefully the winners fight the winners," added Hearn.
