Anthony Joshua has warned Oleksandr Usyk to mix up his fighting style against Derek Chisora, suggesting “some people don’t respect” his approach.
Usyk, a former undisputed cruiserweight champion, will contest just his second fight at heavyweight on Saturday against Chisora.
The Ukrainian defeated Chazz Witherspoon in Chicago last year but faces a sterner test in the form of Chisora, unbeaten in his three bouts since being knocked out by Dillian Whyte in London two years ago.
Usyk is the mandatory challenger to Joshua’s WBO belt and is expected to be given a title shot next year, but the Briton feels he must display some greater raw punching power if he is to thrive in the heavyweight division.
“When I boxed Andy Ruiz Jr. in the second fight, I adapted to the Usyk style,” Joshua told Sky Sports. “Hit and don’t get hit, the sweet science of boxing. You learn that from the amateurs.
“I was amateur for 2 1/2 years so was still adapting to different styles. Usyk was amateur for a long time so he has taken the ‘Hit and don’t get hit’ style into the pros.
“The good thing that helped me? Sometimes I know to sit down on my feet and hurt someone.
“You’ve got to let them know that you’re there because all that pitty-patty stuff after 12 rounds? Sometimes people don’t respect that type of power.”
Joshua will put his IBF, WBA and WBO titles on the line against Kubrat Pulev on Dec. 12 and is set to face the first of a unifying doubleheader with Tyson Fury in 2021.
But Alexander Krassyuk, Usyk’s co-promoter, says an agreement is in place for the winner of Joshua-Pulev to face his man next.
“Our plan is: a.) Beat Derek Chisora; b.) Push AJ to comply with WBO rules or vacate the title; c.) Defeat AJ or any other WBO champion or contender and become the heavyweight champion. Simple and practical,” he said.
