"What sickens me is that the little motherf***er is retired now, " McGregor said in a Q & A during the "An Evening with Conor McGregor".
"He's 50-0 and getting on, I'm not calling him out". I'm gonna leave him to it.
"I've since fought the Floyd [Mayweather] fight and who knows what's next - keep an eye out for a sequel!"
"If we had a rematch?"
'We haven't spoken (since the fight).
"I earned their respect and put myself out there". I accept [the loss] and just let him be. Maybe we can persuade one of these boxing opponents to step into the Octagon or there's also boxing belts as well.
For now, the Irishman has his sights firmly set on returning to the octagon but is not ruling out a return to the ring further down the line.
With that fight now in the rear view mirror, McGregor seems prepared to resume his career in the UFC where he is currently the reigning lightweight champion.
"I've got everyone clawing at me, trying to get at me, and that's from multiple sports, multiple organisations, multiple everything, " McGregor added.
McGregor, speaking ahead of the Dublin premiere of "Conor McGregor:Notorious" - a documentary about the fighter - said his next fight would be to defend his Ultimate Fighting Championship (UFC) lightweight title. There are many boxing contenders as well.
But October 7, 2017 saw the crowning of a new interim UFC Lightweight champion in the form of Tony Ferguson, who notched his tenth win in a row and is nearly certainly the next in-line to step up to "Mystic Mac". "But the next fight will be to defend my UFC lightweight belt". I feel that will be next. "Maybe, though. Who knows, we'll see".
The 29-year old has also not ruled out completing a trilogy with long-time rival Nate Diaz.
"Ideally I would like to take one of the boxers into an MMA bout - someone come into my world now".
