Conor McGregor is one of the greatest fighters in UFC history.
The Irish fighter has entered the Octagon 26 times and emerged victorious on 22 occasions.
He's also a world champion in two different weight classes: featherweight and lightweight.
But where does McGregor think he ranks in the top four best fighters in the sport's history?
On Saturday afternoon, McGregor created a 'Goat thread' where he listed his top four fighters ever in the UFC.
And here's who he thinks are the sport's best ever...
1) Anderson Silva
"The array of finishes, across 2 divisions, with champion status in 1, Anderson Silva is No.1 MMA GOAT," he said of Silva.
"Most stylistic finishes on resume," he added in another tweet. "Front kicks to face. Up elbow (albeit outside UFC) Thai plum knees leading to broken facial bones. Long list of jaw dropping finishes. Myself/Anderson have the most exciting/important finishes in the sport!"
2) Conor McGregor
Yes, McGregor thinks he is the second best ever in the sport's history.
"My array of finishes, across 3 divisions, with champion status in 2, I’m No.2. If not tied 1," he said of himself.
"However still active, No.1 is fully secured by career end. And easily."
He doesn't lack confidence, does he?
3) Georges St-Pierre
"GSP is in at 3," he tweeted. "Much less array of finishes but champion status in 2. He is far behind though.
"Reasons = Left 170 after much damage taken+questionable decision. Never re-engaged 170lb successors. Bottled Anderson fight. Only moved when one eyed fighter presented. Played safe."
4) Jon Jones
"Jon is 4. Maybe tied 3," he wrote. "More array of finishes than 3 and still active, but champion status in just 1.
"Reasons = Multiple lacklustre decision performances + questionable decision win. Attempting to safe play HW entry/avoiding its champion."
McGregor's biggest rival, Khabib Nurmagomedov, did not make it into the top four.
McGregor explained why, writing: "Fancy record but a way to go before any GOAT entry. Only HL is win over me with hangover and broken foot.
"Other than that, made Iaquinta's career with bad performance before Cerrone ended it again. 3rds to get Poirier out. 0 array of finishes. Bottled many bouts. Zero else of note."
McGregor simply can't not stop firing shots at Khabib.
