Though the two have, to this point, engaged in only a mild war of words, Aldo made the general observation during a media conference call Monday that he felt fighters should earn title shots. That could very well have been a veiled swipe at Edgar, who is challenging for the featherweight title in his debut at 145 pounds.
"It doesn't bother me," Aldo said through translator Ed Soares during a UFC 156 media conference call covered by Bleacher Report. "Each person has to try to find a way to create opportunities for themselves in their careers...everybody should go out there and fight and go through opponents, not talk their way into the title."
Aldo went on to flash a bit of his own trash when asked if he thought Edgar, the UFC's former lightweight title holder, won his rematch last summer with current lightweight champ Benson Henderson. Henderson took the decision following a close five-round fight, but many fans and observers believed the decision should have gone to Edgar.
"Not only have I watched it, I've watched it many times," Aldo said through his interpreter. "I do believe that Henderson was better that night."
Also during the call, Aldo squashed any rumors that he is, at least currently, considering a move to lightweight.
"Right now, my focus is strictly on the fight at UFC 156," Aldo said through the interpreter. "I'm 100 percent focused on the fight and giving my best. Once that's over, I'll sit back and think about what my next options will be."
Aldo (21-1) will defend his UFC title for the fourth time at UFC 156. He is known for a well-rounded game, but is particularly feared for his striking skills, particularly a brutal leg-kick attack that has previously felled the likes of former WEC champ Urijah Faber.
Edgar (14-3-1) pointed to Aldo's striking as a threat, but said he respected all phases of Aldo's game.
"He has a lot of tools, especially with his striking," Edgar said on the media conference call. "He has great takedown defense, too. I can't just point out one thing. He's well-rounded."
