RIO DE JANEIRO -- Jose Aldo pulled out from a UFC 189 clash with Conor McGregor in July, but his injury became public weeks after was he finally forced out from the bout.

Slated to meet "The Notorious" on Dec. 12 in Las Vegas, Aldo wonders if someone inside Nova Uniao leaks inside information to the media after former UFC star and current ESPN analyst Chael Sonnen stated he would again pull out from a fight with McGregor due to an injury.

"Man, anything you do people will talk about," Aldo said during a UFC 194 media day in Brazil. "I didn’t care much, ‘Dede’ (Pederneiras) was pissed about it. I try not to care about what people say. But it was good that that happened.

"Everything we do in the gym now we hide from everyone. Sometimes I say I injured something so we can find out who’s the snitch, while we give the wrong clue. I try to stay calm, relaxed, and that’s what really matters. Chael is always talking, so that’s another crap he said."

Focused on his title defense against McGregor, Aldo is still trying to find out if someone around him leaks information, but Sonnen’s statement had nothing to do with it.

"No, I actually don’t know what happened," he said. "I think that came up last week and I was training normally. I brought five Dutch guys with Andy Souwer and we were training normally, training hard. It wasn’t even training, it was something for Sherdog, real fight.

"It was over, I went back home, and when I wake up to train people said I was hurt. But it’s cool, it’s part of the job. No problem. We’re going after the snitch. I’ll cut his head."
