This past Saturday night, Deontay Wilder raised his undefeated record to 39-0 with 38 knockouts by blowing out Bermane Stiverne in the first round to retain his WBC world heavyweight crown at the Barclays Center in Brooklyn, New York.

It was the second time the two fighters have squared off. The first saw Wilder capture the WBC title from Stiverne with a 12-round unanimous decision at the MGM Grand in Las Vegas.

After the fight, Wilder, 32, called out IBF, HBO and WBA champion Anthony Joshua.

"I've been waiting on that fight for a long time now," said Wilder. "I declare war upon you. Do you accept my challenge? ... I've been waiting for a long time. I know I'm the champion. I know I'm the best. Are you up for the test?"

But Joshua's promoter, Eddie Hearn, is more interested in matching his other fighter, Dillian Whyte, in a clash with Wilder on a February date in London.

Former super middleweight champion and Sky Sports pundit Carl Froch would like to see Wilder fight Joshua next. He doesn't believe Whyte is ready for such a fight yet.

"I just think that Joshua beats him. 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," Froch told Sky Sports.

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."
