"Vitor Belfort pulls out of more fights than he agrees to. He's fantastic," said Sonnen, during a recent interview with MMAFighting.com. "He's such a chicken and he's such a liar."
In continuing, Sonnen said, "To say you're going to fight, to sell tickets, to sign your name, to film the TV show, and then to pull out? Against an invalid? That's insane."

Belfort was forced out of a bout with Wanderlei Silva after injuring his hand. The two were coaches opposite one another on The Ultimate Fighter: Brazil.
However, Sonnen did have some nicer remarks for the two Brazilians later on during the interview. It is possible that either fighter could be a future opponent for Sonnen, so maybe he is trying to play a little nice.
"My opinion of Wanderlei is constantly evolving because as atrocious as he is skills-wise, he shows up and fights," Sonnen said. "He goes hard in spite of the lack of talent and gives the fans his best. Vitor's a dork, but he's a tough fighter, man. I really think he's an excellent fighter."
