WBA/WBO/IBO/IBF heavyweight champion Wladimir Klitschko admits that his list of future opponents is starting to run a little thin. Following last Saturday's unanimous decision win over David Haye, Klitschko stated that he's likely going to target the winner of the upcoming heavyweight bout between unbeaten British punchers Dereck Chisora and Tyson Fury, which takes place on July 23.

The slimmer Chris Arreola, returning this Saturday in Atlantic City, has been mentioned by Wladimir as another possible option for a year-end defense. Arreola was stopped a few years ago by older brother Vitali Klitschko, but the Mexican heavyweight has rededicated himself to the sport and cut a lot of fat from his torso.

"If you look around, who is there for me to fight? If you look at the best in the world, the fighter who has the pound for pound title then maybe I should be calling Manny Pacquiao but that would be a mismatch because of our size difference," Wladimir said.
