Who put up the better performance: Haye against Wlad or Chisora against Vitali? *Yes I know they are two different fighters*
Haye underdelivered. Chisora overdelivered. Haye didn't try to win. Chisora tried. Vitali seemed injured or past his best (or both) though, that probably helped Chisora.
Haye is a better fighter than Chisora but out of these 2 fights Chisora easily put up a better performance over achieving compared to Hayes doing **** all really and not risking **** all to get that win.
