We’ve heard this bit from Chael Sonnen (27-13-1 MMA, 6-6 UFC) before, but if the self-proclaimed “Gangster from West Linn, Oregon” is to be believed, he’s waiting to sign a new contract before his headlining bout with Mauricio “Shogun” Rua – and he’s apparently got a list of demands in hand. “My contract with the UFC has expired,” Sonnen said during fan-driven Q&A session at this past weekend’s UFC Fan Expo. “So I went to Dana White, and I went to him with a list of my demands because he’s getting my contract together. He thought this was a gag, but I was being serious because it’s not all about money with me.” Sonnen, of course, remains one of the UFC’s most outspoken characters. He frequently claimed in advance of his UFC July 2012 rematch with Anderson Silva that he hadn’t signed a bout agreement, but the contest went on exactly as planned. As it stands now, Sonnen is scheduled to headline the UFC’s Aug. 17 debut event on FOX Sports 1 against Rua
