Boxing: 'There will definitely be a different result' - Dillian Whyte predicts payback over Alexander Povetkin

British heavyweight Dillian Whyte and Russian rival Alexander Povetkin are taking very different approaches to their long-awaited rematch at Gibralter on Sunday morning (NZ time).

After his stunning victory in their first meeting last August, Povetkin seems prepared to let his gloves do the talking, while Whyte's mouth is more than making up for his rival's reticence.

"It's the biggest fight of my career," Whyte has told BBC Radio 5 Live's Boxing with Costello and Bruce podcast.

"There is no psychological damage. I'll get straight back in and prove to myself how good I am.

"There will definitely be a different result."

Whyte, 32, has weighed in at 112kg - three kilograms lighter than their first encounter - while Povetkin, 41, tips the scales at 103.5kg for the bout billed as 'Rumble on the Rock'.

Seven months ago, the Russian hit the canvas twice in the fourth round, but felled Whyte for good in the fifth, extending his career record to 36 wins/two losses/one draw.

They were scheduled to meet again in November, before Povetkin was hospitalised with COVID-19. That encounter was moved to February, but moved again, with the pandemic restricted international travel.

The previous result deprived Whyte of a shot at the title, and he promises to be more "switched on and focused" this time.

"I could've taken more advantage of those knockdowns in the fourth last time, but that's heavyweight boxing," he says. "If you fight good fighters regularly, you will lose sometimes.

"You have to be ruthless and fearless - that's how guys get up off the floor and win fights.

"I still believe I can be one of the best heavyweights of the day, if not the best out there. I believe I will be world champion one day, but I'll get this done first - I'll knock out."

Perhaps Whyte's most significant victory in a 27-2 career his unanimous decision over Kiwi Joseph Parker, inflicting the former WBO world champion with his second successive defeat, after losing his belt to Anthony Joshua.

By contrast, Povetkin promises only "beautiful, interesting boxing".
