WBC heavyweight champion Deontay Wilder says he will beat Anthony Joshua in his “safe haven” of Great Britain.
Wilder, 32, defended his belt against Bermane Stiverne on Saturday, a week after Joshua retained the WBA and IBF crowns against Carlos Takam in Cardiff.
“Packing out stadiums looks good but the money and Mecca of boxing is in America,” Wilder told BBC Sport.
“But if you want to stay at home like a little girl, this king has no problem travelling to knock out the champion.”
In an interview with BBC Radio 5 live, Wilder accused promoter Eddie Hearn of “brainwashing” British fans with “rumours” that Joshua is the best heavyweight in the world.
“I think Eddie is ducking me more so than Joshua,” Wilder added. “If Joshua’s a strong champion, a true champion, you guys in England should smoke him out, make him fight. You should see if he’s the best.
“My heart says I’m the best, if I’m not I want someone to show me.”
