A video of Conor McGregor training for his UFC return has emerged online and fans are going crazy for it.

McGregor, 35, is set to make his long awaited return to the octagon on June 29, as he takes on Michael Chandler at UFC 303.

The blockbuster showdown will be held in the T-Mobile Arena in Las Vegas, Nevada.

McGregor boasts a record of 22 wins and six defeats – although has only won once since becoming the first fighter to hold two UFC belt’s simultaneously in 2016. Chandler has a record of 23 wins and eight defeats.

The Irish superstar hasn’t fought since breaking his leg three years ago in the trilogy fight against Dustin Poirier – but is looking ‘slick’ according to his long-term trainer Joe Kavanagh.

“He’s looking super slick,” Kavanagh told SevereMMA.

“It’s hard to keep the level of intensity. Even if it’s not physical, the level of mental intensity, of always thinking about training, always thinking about sequences, always thinking about techniques.

“That’s something Conor’s had naturally his whole career. So even though there’s times when he’s off filming, he’s doing this, he’s doing that, we’re still always having conversations back and forth.

“Whereas some fighters are like, ‘If I’m not fighting, I don’t even want to look at shows. I’ll just get ready when there’s a fight coming up.’ That’s really held to him because he’s come back on the mats as sharp as ever. Of course, we’ve got to get the rounds in and get the conditioning up to be ready for competition, but his technique is as sharp as ever.”

Which certainly looks the case after McGregor posted a video of himself sparring on his personal X (formerly Twitter) account.

Fans have since flooded the comments to share their thoughts on the video, with one person saying: “THE MAC IS BACK.” While another added: “Only McGregor can end Makhachev’s reign.”

Others were slightly critical of how he was looking ahead of the fight, after stating: “Footwork needs improvement, left hook looks good though. You’re getting there!”

However, the vast majority of people were just overjoyed to see McGregor back in action. “The KING is back,” another fan said.
