The Russian won the bout via submission with a rear-naked choke in the fourth round, thus handing Notorious the second defeat of his career at the time.
McGregor spoke about the defeat, breaking down every detail of the fight in an Instagram post following the bout.
Despite losing, McGregor was his typical self; pretty positive and adamant that he was having a good fight.
The Irishman said: “Thoughts on my last fight. Round 1. I believe from a sport standpoint, round 1 was his. Top position against the fence. Zero position advancement or damage inflicted. But top position.
“From a fight standpoint the first round is mine. Actual shots landed and a willingness to engage. Straight left early. Knee to the head on the low shot. Elbows in any and all tie up scenarios.
“Opponent just holding the legs against the fence for almost the entire round.”
The Irishman then continued and looked into the second round, where he addressed the fact that Khabib rocked him.
“Round 2 he is running away around the cage before being blessed with a right hand that changed the course of the round, and the fight.
“It was a nice shot. After the shot I bounced back up to engage instantly, but again he dipped under to disengage. That is the sport and it was a smart move that led to a dominant round, so no issue.
“Well played. If I stay switched on and give his stand up even a little more respect, that right hand never gets close and we are talking completely different now. I gave his upright fighting no respect in preparation.
“No specific stand up spars whatsoever. Attacking grapplers/wrestlers only. That won’t happen again. I also gave my attacking grappling no respect. To defence minded. Lessons.
“Listen to nobody but yourself on your skill set. You are the master of your own universe. I am the master of this. I must take my own advice.”
McGregor was then convinced he recovered and won the next round.
“Round 3. After the worst round of my fighting career, I come back and win this round.
“Again walking forward, walking him down and willing to engage.”
Then he went into detail about the final round and where it all went wrong.
“Round 4. My recovery was not where it could have been here. That is my fault.
“Although winning the early exchanges in 4, he dips under again and I end up in a bad position with over 3 on the clock. I work to regain position and end up upright, with my back to the fence. A stable position.
“Here, however, I made a critical error of abandoning my over hook at this crucial time, exposing the back, and I end up beaten fair and square.
“What can I say? It was a great fight and it was my pleasure. I will be back with my confidence high. Fully prepared. If it is not the rematch right away, no problem. I will face the next in line. It’s all me always, anyway. See you soon my fighting fans I love you all.”
After the fight, McGregor was keen for a rematch and often tried to rile Khabib up. However, a second bout between the two never took place.
Given that Khabib has retired now, it looks like the rematch will never take place.
