#3 Chuck Liddell
In terms of popularity, you won't find too many fighters that top Chuck Liddell. The guy is an absolute legend and helped to build the UFC into what it is today.

The reason behind this is that Liddell was seen partying at a nightclub in preparation for the fight, which angered fans who felt he wasn't at 100%.
Liddell probably didn't help matters by unintentionally going full heel and revealing that his behaviour wasn’t dissimilar to any of his other top fights within the world of MMA. That may not have been the best move, Iceman.
