Former world heavyweight champion Tyson Fury insists he loses sleep with the notion that people believe Anthony Joshua and Deontay Wilder are better than him.
Fury, 29, has not fought since claiming the IBF, WBA and WBO titles from Wladimir Klitschko in November 2015.
The British boxer is gearing up for his comeback against Albanian Sefer Seferi on June 9.
“I can’t sleep at night knowing people think AJ is better than me or Deontay Wilder is better than me,” Fury said on Instagram.
Fury’s fellow Briton Joshua is the reigning WBA, IBF and WBO champion while the WBC crown is now held by American Wilder.
Seferi has boxed at cruiserweight for most of his professional career, losing just once in 24 bouts and Fury is predicting that he will rise to the top of the heavyweight division on his return to the ring.
“I will separate them from their senses. I want to hit AJ with six left hooks in a row. I’m more determined than I’ve ever been,” he added.
“If there are any cruiserweights or light heavyweights out there who want to move up into my division you better get it done because I’m smashing through everyone.”
Seferi has boxed four times since Fury was last in the ring in his unification match with Klitschko back in late 2015.
