TYSON FURY insists he won't make the mistake of trying to outbox Oleksandr Usyk in their crunch rematch.
The Wythenshawe warrior's dreams of becoming undisputed heavyweight champion were shattered in his May melee with the Ukrainian, which he lost via split decision.
Fury, 36, insists he only lost the historic Saudi showdown because he was “playing around" with the London 2012 gold medallist.
And the Gypsy King has adopted a kill-or-be-killed mentality for his second straight Riyadh rumble with the slick southpaw.
The former unified heavyweight champion said: "I’ve always been a bad man my whole life, and I’m still one today at nearly 40 years old, a few years off 40.
"I'm going to go in there with destroy mode. Last time I went to box him, I was being cautious.

"Anybody can get caught as we have seen in a lot of these heavyweight fights.
"But this time I'm not going for a points decision. I'm going to knock that motherf****r out."
Fury outrageously claimed Usyk was given the nod in their first fight because of his homeland being "at war" with Russia.
And he's adamant the judges won't give him a fair shake if they go the distance again.

He said: "There's no secret. I'm going in there to knock you out.
"Because I don't think I'm going to get a decision no matter what I do.
"I don't think I'm going to get a boxing decision.
"So I'm going to have to take it out of the judges' hands like I did in America that time [against Deontay Wilder].
"And I've got to get him out of there.
"Hand on heart, I have to get him out of there to see victory."
Fury looks to have beefed up considerably for the do-or-die desert dust-up.
And he's seemingly on course to weigh more than the 18st 7lb he did for his first meeting with the former cruiserweight king.
The dad-of-seven enters the potentially legacy-defining rematch as both a challenger and an underdog for the first time in five years.
But he insists he does his best work when the whole world is counting him out.

He said: "For the first time in years, I'm going in there as a challenger, not a champion.
"And I believe that I'm better as a challenger, always, because I've got that goal of achieving something and it's giving me a fire underneath."
