Conor McGregor has fuelled speculation he is closing in on a rematch with Khabib Nurmagomedov by appearing to have applied for a Russian visa.
The pair, who met in the octagon in October 2018 when Khabib defeated the Dubliner by submission, have been engaged in another bitter social media spat today.
It started when McGregor appeared to take aim at rival Khabib and UFC president Dana White in a random post.
The UFC boss had told the Boston Globe that McGregor was 'not the man' in the promotion anymore, and that his Russian rival had taken over the reigns.

This appeared to prompt McGregor to hit back at both men, alluding to the idea that Nurmagomedov's big title defence in Abu Dhabi against Dustin Poirier was not the 'marquee fight' it's been touted as.
He said: "Who’s not the man? Your man had that marquee event did he? More like an event in a marquee. A tent in the f***ing sand it was.
"Keep spoofing to your self horse. Jock strap sniffer championships."
Khabib hit back by making a tweet in Russian that translated to: "This is a fiasco wino."
McGregor responded in turn by writing a tweet of his own in Russian, which translated to: "See you in Moscow, p****."
And then the Notorious later posted a picture of himself holding what seems to a snap of the Dubliner at a Russian embassy where there is a sign a for visa applications.
Although this could also all be related to McGregor's whiskey brand with the 31-year-old telling his social media followers last weekend that his whiskey had landed in the Russian capital. "See you guys in Moscow," he tweeted.
McGregor has not fought since that 2018 loss to the undefeated Russian in Las Vegas, while Khabib made a triumphant return to the octagon last month when submitting Dustin Poirier in Dubai to defend his lightweight title.
UFC President White has ruled out a rematch coming to fruition, insisting Donald Cerrone or Justin Gaethje could be next for McGregor.
