Dillian Whyte has urged Tyson Fury not to do as he's been promising and engage in an early war with Deontay Wilder this weekend.
Fury twice got up from the canvas to earn a draw in the first fight, dominating rounds to the extent that many felt he'd been hard done by despite being floored on two occasions.
He's since suggested that he'll attack from the off against an opponent whose career has been notable for a string of early and often devastating knockout blows.
Fury told reporters earlier this week that he expects to stop Wilder in two rounds, and compatriot Whyte isn't certain it's a bluff.
"He talks a lot of crap but he's crazy enough to actually try it!" he told Sky Bet ahead of Saturday's heavyweight spectacular.
"I think that's very dangerous - if his coaches advise him to do that, you need to really have a look at his corner.
"He can stop (Wilder) late in the fight, but if he tries to trade with him early he gets knocked out."
Wilder has promised to stop Fury this time having thought he'd done so in the final round of their first meeting, but Whyte insists he can't keep relying on one punch.
When last in action, the American knocked out Luis Ortiz in the seventh round at a time when he was behind on all three of the judges' scorecards.
"He needs a bit of consistency - he can't just rely on the one big punch," added Whyte.
"He's having more and more trouble over the years, people are realising 'ok, this guy's a one-trick pony, I just need to keep him moving and keep boxing.'"
As for who comes out on top, the WBC interim heavyweight champion says it all depends on whether Fury is true to his word, or picks his shots and outboxes his opponent.
"I see more holes in Fury than another person might. It's very difficult. I wouldn't be surprised if there's another draw again.
"If Fury is stupid enough to try and trade with Wilder early, he gets knocked out. But if he's smart, if he boxes and does what he usually does, I pick him to win on points."
Whyte is eyeing a big fight of his own in the coming months, though remains sceptical as to whether he'll get his wish and a third meeting with rival Anthony Joshua.
"If Joshua wants to fight, I'll fight him. If he wants to fight, I'll fight him tomorrow. Anyone in the top 10 who wants a fight and it makes sense, I'll fight them, I don't care."
