he has very little chance against a tall guy. I see him jabeed to death from a taller guy who can jab effectively. However, I think he beats Chisora fare and square at that point. I would bet on the old Chisroa to beat him but David Haye damadged Chisora so bad that his pucn resistance is now gone...
technically very good for a heavyweight and has a hell of a chin, could go far, has a good of a chance against wlad as anyone
Perez poses the biggest threat to Klitschko at this moment. His chin is pure iron, warrior pur sang and he has power.
