Right now Chisora kills him. Any dude that can back up a klit is not going to have a problem walking threw Mitchell. That being said Chisora is already world level. Mitchell is a work in progress and he seems to have a lot of good qualities.
Respect to Mitchell he showed a lot of heart and loved his bodywork in the 2nd round, im a fan and look forward to seeing him fight again. Shame his chin seems shaky.
Mitchell would kill him. He hits to hard for a face-first hands down fighter. Chisora has no power and he's 15-3. People are down on Mitchell's chin, but he never went down, and wasn't even seriously hurt, just wobbled. It also happened in the first round when a lot of guys aren't warm yet. (Amir Mansour would beat either, too bad he's in jail.)
