I like both guys, too, and I think it's going to be a great technical fight. Gus will have the home land advantage again! I am looking very forward to see how Mousasi does in this fight. I hate for either of them to lose right now though.
Gus is definitely the number one contender right now, however, if Hendo were to knock Machida out, he would be neck to neck with Gus, IMO.
