Great news. Wasn't interested in Sonnen vs. Munoz, simply because I want to see Sonnen vs. Silva 2. I think Munoz could've defeated Sonnen since they can cancel each other out in wrestling but Munoz has much better stand up.
Now, Sonnen has a better chance to win against Bisping. IMO, Bisping cannot deal with Sonnen level of wrestling and doesn't have neither enough power to KO him nor enough skill to submit him.
