Undefeated WBC heavyweight champion Deontay Wilder has thrown down the gauntlet to Anthony Joshua after devastating Bermane Stiverne in a mandatory defence of his title last night.

After knocking his opponent out in a brutal first round at the Barclays Centre in Brooklyn, the US boxer called out to his British rival: "I declare war on you. Do you accept my challenge?"
