Conor McGregor is set to face his toughest challenge yet on Dec. 12 in a featherweight title unification fight against Jose Aldo. But that didn't stop the brash Irishman from making his plans beyond that fight known.

"I hoping Jose will show up," McGregor said at a downtown L.A. media event. "I'm going to retire him, end his career, and then I've done what I've said I'll do. I said I'm going to kill the featherweight division, there's nobody left."

McGregor has made it no secret in the past that he doesn't plan on staying long at the 145-pound division, but he also clarified during the media event that there's one more fight that could keep him at featherweight.

"If Frankie [Edgar] was to put on a phenomenal performance and stop Chad [Mendes], or maybe something like that, then I can say, alright, let's answer the Frankie question, let's shut him down real quick," McGregor said referring to the Edgar-Mendes tiff set a day before his fight against Aldo.

"But in my mind, I'm thinking I'm going to unify the belts, I'm going to destroy the division, and then I'm going to take the lightweight division as well. That's where I'm headed right now."

He adds, "I wouldn't want to fight a lightweight guy to get the numbers because who the f---, Rafael [dos Anjos] has nothing. Rafael will be looking to make six figures this fight, and rightfully so. He shouldn't even make six figures because he doesn't even bring in six figures. Donald [Cerrone] will scrape six figures because he shows up and fights every couple of weeks. But he don't earn much more than that. I already have the numbers, so when I go to the lightweight division, it will be to gain more gold, to warm up my other shoulder."
