Fighters Only provides the translation of an interview with the champion:

D24AM: What did you make of Chael Sonnen’s statement that Wanderlei Silva would be selling barbecue in Manaus if he weren’t in UFC?

Jose Aldo Jr: Coming from Sonnen... he is a clown who speaks so much junk. Speaks things that he couldn’t and doesn’t know. If he says it in front of an amazonense (native from Amazonas) it can create a problem. Blood boils.

Wanderlei already answered. I already was with Sonnen. He speaks for self-promotion but this is going beyond the point. This is bad for his image and damages our image. There (in the U.S.) they think there are only Indians and alligators in the streets [of Amazonia] but it is changing. You can’t write what Sonnen says. Let him speak [expletive]...

Chael Sonnen knows how to get under people's skin, that is certain.  Why not put Chael Sonnen on the card in Rio, and let him get acquainted with his numerous fans in Brazil?  Well, that's doubtful, but locking him in a cage with Wanderlei Silva is just as good.
