The coaching matchup between Chael Sonnen and Wanderlei Silva looked like dynamite television waiting to happen, but things went south early on in filming, flipping on its head what looked set to be a classic “TUF” rivalry. As one of the brashest trash talkers in the history of the sport, Sonnen had a knack of getting under people’s skin. His witty banter and snappy one-liners resulted in him becoming one of the biggest draws and “heel” characters in the promotion. His most infamous rivalry was undoubtedly with UFC middleweight champion Anderson Silva, with the peak coming when Sonnen took aim at the Brazilian legend’s country, family, and legacy. But, despite Sonnen (31-17-1 MMA, 7-7 UFC) squashing the beef with “The Spider” after falling short in their two championship battles, he found himself in another heated rivalry, this time with Wanderlei (35-14-1 MMA, 5-7 UFC). Sonnen and Wanderlei filmed Season 3 of “The Ultimate Fighter Brazil,” where things got physical between the pair after Sonnen refused to apologize for criticizing Brazil during his past rivalry with Anderson.
