Dillian Whyte says he was 'bossing' Alexander Povetkin before his shocking knockout and quickly requested a rematch.
The Brixton heavyweight appeared to be on the brink of victory after flooring Povetkin for the second time in the fourth round but was then sent crashing to the canvas by a massive uppercut in the fifth.
Whyte's plans for a mandatory fight with Tyson Fury have been shattered, but he still wants to gain revenge on Povetkin before the end of the year.
He told promoter Eddie Hearn via Matchroom Boxing's Instagram: "Can we get the rematch in December?
"Okay cool. I'm good, I'm good, it's one of the things where he just landed.
"I was bossing it.
"It is what it is. Rematch, it's all good. That's what heavyweight boxing is about."
The Matchroom boxing boss has confirmed Whyte can activate a clause in his contract for a rematch.
Hearn told Sky Sports Boxing: "The first thing Dillian said was 'Get me that rematch, get me that rematch.
"Povetkin is mandatory now, but the only person who would get called to negotiate to fight the winner of Fury-Wilder was Dillian Whyte.
"We'll exercise that rematch clause. We'll look to make that before the end of the year and it's a huge fight."
Anthony Joshua questioned Dillian Whyte's ruthless instinct after a knockout loss to Alexander Povetkin.
The Brixton heavyweight's hopes of a shot at Tyson Fury's WBC belt were shattered by Povetkin, who brutally ended the fight with a huge uppercut in the fifth round at Fight Camp.
Joshua had stopped the Russian in their world title fight in 2018 and questioned why Whyte did not pursue a knockout himself after flooring Povetkin for the second time in the fourth round.
The unified champion told Sky Sports Box Office: "I asked [Sky Sports expert] Johnny (Nelson), 'Does Dillian still have that instinct in him?' Because the fight was called maximum violence.
"When he had the opportunity to take him out, I wanted to see that maximum violence.
"That's why for me, when I smell blood, I go in there to take someone out, but sometimes you can get caught in the exchange.
"But at the end of the day, if you leave it a round or two later, as we've seen there anything can happen.
"The tactic go out the window. You've just got to remember this is a fight, you've got to take the man out and move on to the next."
Promoter Eddie Hearn had even suggested Whyte could have received an undisputed world title fight with Joshua if Fury had not fulfilled a mandatory title defense.
But Whyte will instead pursue a rematch with Povetkin and Joshua urged him to set aside any stinging criticism.
"Dillian spent months and months in Portugal training and something like that can happen," said Joshua.
"But I feel like the training doesn't add up to this fight with Povektin, he's got another how many years in the sport.
"This is just a blip in the career. People are going to talk about all sorts of stuff about Dillian.
"Dillian is a fighter, I stick with him as a fighter and say, 'dust yourself off, get back up, and go again.'"
