Bellator heavyweight Chael Sonnen has garnered some heat from fellow fighters during his lengthy mixed martial arts career. From a heated rivalry with Wanderlei Silva to an intense trash-talking spree with Anderson Silva, Sonnen has locked horns with some of the sport's greatest. Speaking to Gol.hr in a former interview years back, MMA veteran and Pride legend Mirko Cro Cop dished out some heated words of his own concerning Chael Sonnen. "I don't want your viewers to get offended." Cro Cop said. "I am not the creator of any anthropological theories, but you can tell by his face that the man is slow -- that he is stupid and he has the IQ of a children's shoe size. You can tell this by his face." Chael Sonnen is now set to face off against heavyweight MMA legend Fedor Emelianenko in the semi-finals of Bellator MMA's heavyweight tournament grand prix. The bout will take place Oct. 13 at Bellator 208. For more MMA news click here.
