In a recent interview with UOL Esportes, Silva talked about Sonnen and many other topics (transcription by Orcus).
On Sonnen:
A lot of people who hears the crap he says end up thinking; "I don't like MMA, it's a joke." What he does only hurts the sport in general. That's never good. We are in a good phase with MMA and we have to capitalize on it. It looks like Chael doesn't understand that, all he wants is for people to get angry.
On getting older:
Im no longer the same, everything hurts and it takes much longer for me to recover (from injuries).
On a potential superfight with Georges St. Pierre:
GSP is very educated and I like him a lot. A fight against him would be very, very, very big and this could actually happen.
On fighting Jon Jones:
I don't plan on moving up in weight anymore. He's in a different weight (class). I train with bigger guys, such as Lyoto Machida and Big Nog and I know how complicated it is. ...Every time I see Jones I tell him to keep focus, because if he does that, there's no opponent for him. He's better than everyone. He'd have a lot of advantages (over me), he's much younger and it wouldn't be something interesting (for me).
