The Briton and Ukrainian will determine the first outright heavyweight champion since 1999 on May 18 in Yar Riyadh, Saudi Arabia.
"Oleksandr Usyk is a real villain. He can only be underestimated by a fool. That's why I'm training hard and doing my best. I respect Usik and his career. I'm looking forward to the fight.
He works well with his feet, he has great boxing skills, technique. He's proven he can fight big heavyweights with wins over Anthony Joshua and Daniel Dubois. This is an elite fighter," Fury said in an interview with Frank Warren's Queensberry Promotions YouTube channel.
