Prior to UFC 142 in Rio, Aldo appeared to be fine with the idea of moving up in weight while talking to Terra Esportes:

It’s been a while that I’ve been saying that I should move up (in weight), to test myself in the above division. But Dedé (Pederneiras) is the one who decides that. When they think it’s the right moment I’ll move up.

But his trainer didn’t seem like he’d concede to that idea:

We don’t think about changing divisions, the focus is all directed to Chad Mendes (right now). When this fight is over, we’ll start thinking about the next (fight). To be honest, I don’t see him moving up in weight, no.

Well, the fight is over and Dede doesn’t seem to have changed his mind:

He’s not going to be moving up in weight for now, unless if it’s for the title, then it’s okay. But to give up his title and to fight his way in the division above his? Forget it. If it’s up to me that’s not going to happen. Unless he goes train somewhere else and someone allows him to do that, I’m not going to allow him to do that.
