Anthony Joshua is set to take on Deontay Wilder next year amid rumours that he is reluctant against taking on the hard puncher.
Deontay Wilder and Anthony Joshua
Britain's Anthony Joshua has said he wants to fight WBC Heavyweight Champion Deontay Wilder in April.
Earlier this month, Joshua watched on as Wilder and Fury fought a thrilling draw in Los Angeles.
MySportDab report the WBC have since sanctioned a direct rematch.
Speaking on American show First Take, Joshua said: "April 13, in London. I don't know what more I have to do to get that message across.
"He's (Wilder) more interested in fighting Tyson Fury - Tyson Fury holds no world titles.
"I can't control what Deontay Wilder does, what Tyson Fury does, or what they say. What I can do is control what I do and say.
"I made sure with the negotiations I booked the date in advance, the venue in advance, and am making my point clear for everyone, I am willing to fight any one of these guys, especially the champion Deontay Wilder, at Wembley, April 13."
