Derek aims for Dubois fight Famous British heavyweight Dereck Chisora wants to fight IBF world champion Daniel Dubois. “I want to fight Dubois for the world title at Wembley. We will sell out this stadium. I want big fights for big business. For that I need Daniel. Usyk and this guy can't sell out Wembley, but I can,” Chisora said. Usyk defeated Chisora in 2020 by unanimous decision. This was Alexander's second fight at heavyweight. In his last fight, Chisora won a spectacular victory against Swedish heavyweight Otto Wallin.
