Bisping lost to Sonnen earlier this year in a closely-contested decision that vaulted Sonnen into the title shot.
Florian, meanwhile, is a multi-time contender for UFC gold and recently-retired fighter.
“People are going to think I’m crazy, but I am going with Chael Sonnen the trash-talker. Chael is getting this,” Florian said.
Bisping said, “I agree, Chael is getting this.”
So, while the majority of the world believes the betting favorite, Silva, will win, there are at least two people in the UFC backing Sonnen.
