Among the boisterous Irishman's visions and loudmouth persona is a desire to be a two-division champion, which first starts at the UFC 194 pay-per-view (PPV) event on Dec. 12, 2015 against current 145-pound king Jose Aldo (full fight card here).
And .. after all, McGregor still has some "unfinished business" with previous foe Max Holloway, who takes on Jeremy Stephens on the same upcoming fight card inside MGM Grand Garden Arena in Las Vegas, Nevada.
"Blessed," who took home a first-round, technical knockout (doctor stoppage) victory over Charles Oliveira at UFC Fight Night 74 back in August, dropped his only loss in two years to "The Notorious" one.
His thoughts on their Aug. 2013 tilt at UFC Fight Night 26 (via FOX Sports):
"Our last fight, I got no excuses, but everybody saying he fought me on one leg and that's why he didn't finish me. Well, let's run it back. Most people didn't know I got injured in the first 30 seconds and he got injured in the last couple of seconds in the second round and the last time I checked he's been finishing everybody in under two rounds. So what's his excuse for not being able to do that to me?"
An ACL injury took McGregor out of a UFC cage for 11 months, following his unanimous-decision win over the Hawaiian. Then, he continued to dominate the 145-pound division by pounding out the likes of Dustin Poirier, Dennis Siver, and Chad Mendes.
Holloway has been equally impressive and has gone on to win seven straight inside the Octagon, including finishes of Cub Swanson and Akira Corassani. The 23-year-old future star is nearing title-shot territory and is ranked as the No. 5 featherweight in UFC's official rankings.
While McGregor has proclaimed himself the real champion, Holloway proposes he first defeat Aldo and unify the featherweight belts.
The Dublin native, whose only signature victory over a top-five opponent is Mendes, has left Holloway scratching his head as to why the former is in such a rush to leave the division.
"The only reason he would want to leave the division is he's a big boy and the weight cut is getting to him. At the end of the day there are a lot of great match ups," said Holloway. "He wants to talk about money, he wants to talk numbers -- Holloway vs. McGregor 2, I think that would make a lot of numbers."
He also hopes "Junior" makes it to UFC 194 unscathed (their UFC 189 debacle here and here). If that were not to be in the cards, Holloway -- along with Frankie Edgar -- would have no problem stepping in and facing McGregor, according to his manager Brian Butler.
Another thing McGregor and UFC like: Big stadium shows. Time and resources have been the road block in an effort to get McGregor to headline a Croke Park event in Dublin.
Why not Aloha Stadium, former site of the NFL Pro Bowl, says Holloway?
"This guy wants to fill a stadium -- well I've got a stadium in mind. It's called the Aloha Stadium in Hawaii. So let's do it. 60,000 plus people and we can fill it up," Holloway said.
Holloway may not have the inside track on a bout versus McGregor; as the aforementioned Edgar might have a thing or two to say about that. Heck, just prior to Stephens being named Holloway's UFC 194 opponent, Edgar 'answer'ed an invitation from the latter to be his Octagon dance partner.
Holloway does hold one important promotional advantage over Edgar in the battle to get to McGregor: he's already gone the distance with him before.
"When you look at our fight, I remember one guy falling down and it wasn't me," said Holloway. "We'll see what happens. I think that eats him up that he didn't get the finish. I do recall him saying at the post-fight press conference saying that he felt he lost the fight with the way he performed, so why wouldn't he want to avenge a loss?
He still has to get past Jose first, so one step at a time. But all I'm saying is don't go running from the division yet."
