Deontay Wilder enhanced his reputation with a devastating first-round knockout against Canada’s Bermane Stiverne on Saturday night.
The 32-year-old retained his WBC heavyweight title in style, knocking Stiverne out with a succession of brutal punches, including a left-right combination.
Wilder now has his sights firmly set on a mega-money bout against Britain’s Anthony Joshua, who recorded the 20th victory of his career against Carlos Takam last weekend.
"I know I am the best. Are you up for the test?" Wilder asked of WBA and IBF heavyweight champion Joshua following his latest victory. "I've been waiting on that fight for a long time now.
"I declare war upon you. Do you accept my challenge?"
How AJ reacted to Wilder's call-out
Although Joshua has yet to respond to Wilder’s request, promoter Eddie Hearn revealed how the 28-year-old’s reacted after exchanging text messages with British boxing’s golden boy.
"I think 2018, we want to see Deontay Wilder against Anthony Joshua, no question," Hearn told Sky Sports. "I was really interested to see the weight of Deontay Wilder on the scales, 15st 9. I texted that to Anthony today, Deontay Wilder, 15st 9.
"I shouldn't really tell you the reply, but it was 'I'll eat him,' and the size difference is huge. It's two-and-a-half stone now between those two."
Carl Froch knows which fighter would win
So, who would win in a fight between Joshua and Wilder?
Carl Froch reckons he has the answer…
“I just think that Joshua beats him,” the four-time world champion told Sky Sports. “I think it's a great fight, a tough fight, but one that Joshua can win. For selfish reasons, as a boxing fan, I would prefer to see Joshua in with Deontay Wilder rather than Dillian Whyte.
“I think Whyte needs a couple more fights. I'm not saying he's not good enough and he won't be good enough, but he laboured to a 12-round win at the weekend. He looked okay, I scored him winning most of the rounds, but I don't think he's ready for Wilder yet.”
Wilder wants Joshua - not Whyte
It seems Wilder himself also has no desire to fight Whyte.
"They are trying to give me a peasant in Whyte,” he was quoted as saying by BBC Sport. “A king doesn't chase the peasants. A king takes kings. I want Joshua. If he doesn't give me the fight we have other plans.”
