St-Pierre, 32, explained that he's interested in returning to the UFC sometime in the near future, if certain things happen to change.
He didn't delve into what exactly those "things" are, but it's likely he was referring to the promotion's stance on drug testing.
After all, that's the reason St-Pierre left the UFC in the first place.
"I’m not sure," St-Pierre said when asked if he will return to the UFC one day. "I see what’s going on in MMA and I like the fact that I don’t have to think about it. I just want to step aside and watch them fight, see what’s going to happen and a bunch other things I can’t say right now (laughs). Maybe, one day, if the things happen like I think they should happen, I’ll return. I don’t know how long it may take, but I’m waiting.
"I got to a point in my career that, even though I loved the belt, I wasn’t fighting for it anymore. It had more to do with my opponent and the challenge. I rather fight a better fighter with no title on the line than fighting a regular fighter in a title fight. The fight itself is what interests me the most."
St-Pierre also says he would be open to fighting Silva when he returns. A superfight between St-Pierre and Silva has been teased for years, but it never came to fruition.
While that fight may have lost some of its original glow since Silva is coming off back-to-back losses and St-Pierre is coming off controversial win, it would still be a fun fight for the fans.
"There’s always a possibility," St-Pierre said of a superfight with Silva. "Some fighters want to fight me because of my name, others for the money. I would fight Anderson Silva. I would even fight Brock Lesnar if it’s a fair fight for both. I’m not afraid of anyone, but I’m not stupid (laughs). Many people think that a fight shows who’s the toughest, but that’s not my case. I see things in a professional and intelligent way."
