The Briton and the Ukrainian will fight for all the belts in the super heavyweight division on May 18 in Riyadh, Saudi Arabia.
"He's the biggest and most athletic boxer I or anyone else has ever seen. We're talking about a guy who is 206 centimeters tall and under 120 kilograms. He's very athletic. He's got great head work, quick hands. Since he joined Kronk Gym, he's become more aggressive and has had a few knockouts.
He's never been a superpuncher. He doesn't have a big single punch, but he's a crafty puncher. He sets traps, he has a high boxing IQ, but there remains a question on form. To win this fight, he will have to neutralize all of Usyk's agility, all of Usyk's intelligence," Algieri told Probox TV.
