If you were Alexander Dimitrenko,

I all honesty, Dimitrenko doesn't have a great talent. Wlad, even when he lost to Purrity at age 21, was an Olympic gold medalist with great athletic gifts. Dimitrenko struggled with a very old and tired Hoffmann, landed a perfect body shot against Krasniqi (but how many fights does a fighter win like this in a whole career? Dimitrenko would have needed to make the fight with Chambers into a street brawl and he didn't have the deisre to do that. With his lack of superior talent, he would need a Holyfield - level of desire to excell at the world level.
