It's been over five months since the now-infamous UFC 229, in which the real fight was upstaged by a chaotic scuffle inside and outside the octagon. Conor McGregor was decisively beaten by his opponent, Khabib Nurmagomedov, despite the months of trash talk he and his team had spread.

It's part and parcel for McGregor, who utilises his insults, jibes and self-promotion as a sort of superpower - and he's got the money to back it up. The Irish fighter's coach, John Kavanagh, said as much in an interview with Joe Rogan in October, where he spoke about Conor's penchant for messing with his opponents:

"Conor's a divider. Some people love it and some people hate it. I'm not really interested in people's opinions, I'm more interested in what is, and what is is that sells fights. There's a reason he's the highest paid guy. That's natural for him to do too, it's not an act."

"It's just part of the game for him, he enjoys it, it's a bit of fun."

It's not like he's let up since his fight with Khabib, either. Within minutes of thanking the Nevada Athletic Commission for dealing with him fairly after his temporary ban from the sport, he still hyped up the fact he got the "final blow of the night" during the post-match brawl.

He's still talking about that fight, months later - but there's even older fights that he still hasn't had the final word on.

Floyd Mayweather Jr. isn't a stranger to hyping himself up or mocking his opponents, so there was a lot of talk before the boxer took on McGregor for their insanely lucrative fight in 2017. But Conor still has something to say about it.

It all started when Twitter user 'mmaballer13' posted a gif from the Mayweather fight, depicting a slow-motion look at some of McGregor's best hits of the night. "That fight was completely Conor's fight through 8.5 rounds," they wrote. "Dang. So close. Rematch anyone?"

That's when Conor, no stranger to weighing in on his fights on social media, jumped into the fray. Retweeting the post, he added:

"I spoiled it with the rush right hook here. The angle was made. He was in the dirt. I just had to set correctly into my feet and fire. Rushing the right hook I lost balance on my back hand. Great boxing fight! A rematch will be interesting no doubt."

Of course, the thing that piqued most UFC fans' interest was that last comment, in which McGregor made it sound like a rematch may actually be on the way.

He's said in the past that a rematch would be on his turf in the octagon, where he would undoubtedly have a great advantage, but it's unclear whether Mayweather will opt for another boxing match instead. Or, maybe he'll end up taking on Khabib again instead.

It would be fair to say that 2019 was a challenging year for Conor McGregor.

Fresh off a devastating defeat to Khabib Nurmagomedov by way of submission in October of 2018, the Crumlin-born fighter made headlines more for his actions outside of the octagon than any exploits in it.

Despite successfully launching his own brand of Irish whisky - Proper Twelve - Conor has had a tumultuous year that culminated in allegations of assault after a video appeared to show him striking a man in an Irish pub.

Conor McGregor was mocked recently for appearing this bizarre Russian advert:

In an interview with ESPN's Ariel Helwani in the wake of the incident, the Irish fighter was contrite, stating;

"In reality, it doesn't matter what happened there. I was in the wrong. That man deserved to enjoy his time in the pub without having it to end the way it did. And although it was five months ago, I tried to make amends, and I made amends back then. But that does not even matter. I was in the wrong. I must come here before you and take accountability and take responsibility. I owe it to the people that have been supporting me. I owe it to my mother, my father, my family. I owe it to the people who trained me in martial arts."

CCTV footage shows Conor McGregor smashing a fan's phone:

He also spoke out on his future in the UFC, saying at the the time that he was game to fight anyone. Back then, it seemed most likely that he would face Justin Gaethje, but we now know that Conor will be making his UFC return at welterweight against Donald 'Cowboy' Cerrone.

This marks Conor's return to the 170lb weight limit - the same weight at which he fought out two monumental scraps with Nate Diaz - and it's fair to say that the Irishman is looking absolutely ripped as he makes his final preparations for the comeback.

Conor will make his return to UFC action on January 18 against Donald Cerrone as the main event at UFC 246.

Conor McGregor has certainly had a successful year. The Irish-born mixed martial arts fighter is estimated to have earned just shy of $100 million in last year, and isn't exactly quiet about it. Always getting into trouble and with a hell of a lot of bravado to boot, he's become one of the biggest stars in the sport for a reason.

In 2017, McGregor was the most searched athlete on Google in the US, undoubtedly because of his recent forays into unexplored avenues. He even stepped out of the sport to take on Floyd Mayweather in the boxing ring, with the event becoming the highest-grossing fight of all time. And while he lost, he looks like he's living pretty well off the stupendous amount of money he made, and is happy to go in the ring for a re-match.

Back in November, at Glasgow's An Evening with the Notorious Conor McGregor, he spoke about Mayweather and his odds at beating him in the future:

"What’s sickening me is that the little [expletive] is retired now. That’s what sickening me.

"I know if I went another go with him, under boxing rules, I'd get that win. I know that. I know after feeling him in that first fight, he had to change his whole approach. He couldn't figure out what I was doing early on. I feel with the lessons I learned, if I had another go around, I'd get it."

"Originally he [Mayweather] said an MMA bout next. He was talking about an MMA fight next," McGregor continued. "That's what he said before the fight. So, what’s that about?"

However, whether or not Mayweather and McGregor reunite to fight it out in one sport or another, McGregor still has plenty of work to get on with. Next month he will be facing off against Khabib Nurmagomedov, the current UFC lightweight champion.

UFC 229 takes place on October 6, and will see McGregor's fight headline the night. McGregor captured the lightweight title at UFC 205 back in 2016, but never defended the title, as he took time off last year due to the birth of his first son. It looks to be a popular night for fans of the sport, and an intense match between the two champions.

However, there hasn't exactly been much fanfare so far - at least, until McGregor released this montage of his training for the fight:

In the clip above, which the star shared without a caption to his Instagram page, McGregor can be seen doing drills, sparring, and conditioning.

Dropping this training montage may be the beginning of the hype cycle, but so far neither McGregor nor Nurmagomedov has said much about the fight. The UFC is reportedly frustrated with the lack of promotion over the upcoming fight, but this is likely to change once the first press conference comes around, knowing McGregor's personality.
