4. Carlos Condit
While these two top fighters met back at UFC 143 with Diaz ultimately unsuccessful in a five-round war, you can be sure Diaz would love a chance to redeem his loss to Condit if given the opportunity to throw down with him once again.
Condit defeated Diaz via split decision at UFC 143 for the interim welterweight title, where the winner would go on to unify the belts against the then-reigning champion Georges St-Pierre.
Condit is coming off of arguably, one of the greatest 170-pound title fights in UFC history when he threw down with champion Robbie Lawler at UFC 195.
‘The Natural Born Killer’ has since contemplated retirement; however he has claimed he would consider stepping back into the Octagon for a big fight, and named a Diaz rematch as one that definitely intrigues him.
