Dillian Whyte remains unconvinced he will get the chance to fight Tyson Fury, saying the reigning WBC heavyweight champion "talks a lot of rubbish" as he waits for a shot at the title.
Whyte is the governing body's interim champion, but it remains unclear exactly when he will get to fight the holder of the belt - if at all.
Fury is set to face Deontay Wilder next, having dethroned his rival earlier this year with a sensational stoppage win. A third bout between the pair is scheduled to happen, though a date for the trilogy is yet to be confirmed.
The winner of that meeting has been ordered by the WBC to next face Whyte, who goes up against Alexander Povetkin on Saturday as he patiently stands by for his opportunity.
However, the mandatory challenger is not sure Fury will sign up to face him in 2021.
"One minute he says he will fight me, the next minute he says he won't," Whyte said during a media conference call.
"Tyson talks a lot of rubbish - he just says whatever he thinks.
"He's someone who doesn't stick to anything he says, he's always saying something today and then something else tomorrow.
"His mind is like the wind - it changes direction every few seconds."
Whyte has agreed to take on the dangerous Povetkin in the fourth and final event in Matchroom's Fight Camp series, staged at the promotion's headquarters in Essex.
The Russian has only lost twice in his career - to Anthony Joshua and Wladimir Klitschko – but Whyte is prepared for anything Povetkin throws his way.
"It's a hard fight - no one can ever say Povetkin is an easy fight. We've seen what he does, he’s been consistent for 15 years at this level. He's beaten top guys," Whyte said.
"He gave Anthony Joshua a problem a year ago, he gave Wladimir Klitschko a problem a few years ago. He's a very strong, very determined guy, technically sound and carries a good punch.
"People say he's 40, but guys are going on longer and being stronger and fighting a lot better as they got older these days.
"They are probably looking and me and think I make technical mistakes, and other things, I know they think they can beat me and stop me, so who knows what their game plan is?
"He might come out and try and go for it early, he might and try and wait and go for it down the stretch. I’m prepared for whatever.
"If it needs to be a 12-round war or a boxing fight, whatever, or a destruction, I'm prepared for whatever."
