UFC fans claim Conor McGregor 'embarrassed' himself after seeing what he did in viral training footage

Conor McGregor has been described as a 'gym bully' by UFC fans after seeing what he did in his latest training video.

McGregor hasn't fought in the UFC since July 2021, but he's hoping to return to the famed Octagon next year.

The 37-year-old is eyeing a spot on the proposed White House card, with Dana White revealing what he has been telling him.

McGregor is currently in Italy and training for his potential UFC comeback.

He's been sparring all comers, including an 'undersized amateur fighter' who attempted a takedown on the former UFC double champion.

Not to mention young, aspiring fighters.

And McGregor didn't hold back during his spars.

A video, which has gone viral, shows the 'Notorious' roughhousing fighters, landing heavy shots during a series of intense spars.

UFC fans on social media called out McGregor, with former Bellator champion Ben Askren also weighing in on the damning footage.

Askren wrote: "What does beating up fighters who aren’t good prove or do to make you better? These videos are so dumb."

A UFC fan claimed: "He has officially reached the old drunk has-been gym bully stage of his career."

A second added: "McGregor beating up 12 year old kids - what a downfall."

A third suggested: "He looks bloated and out of breath."

Daniel Cormier believes 'it's over' for Conor McGregor

McGregor appears hellbent on returning to action, having returned to the drug testing pool.

But UFC legend Daniel Cormier reckons the noise around the Irishman's potential comeback is just to 'stay relevant'.

Cormier claims 'it's over' for McGregor, suggesting he made too much money when he was active in the fight game.

"It's over (for him)," Cormier said of McGregor on Club Shay Shay.

"This dude Conor McGregor, he is tripping. He made way too much (money). He went from plumbing to making – he sold that liquor (company) for what, $500 million? It's too much. He got $100 million for fighting Floyd (Mayweather), then he was doing pay-per-views like nothing. Him and Khabib (Nurmagomedov) did 2.5 million pay-per-view (buys)," he added.

"He made too much money. Conor says he wants to fight all the time, and everybody jumps to it. But it's like, he wants to stay relevant, he wants to stay in the news, he wants the notoriety of being Conor McGregor without having to be Conor McGregor. That kind of sucks because when he was the man, I bet you tapped in. I bet you tapped into the UFC more than ever because he could sell a fight."
