He's sparring, he's grappling, he's knocking people on their asses ... it's impressive stuff.
Of course, Conor hasn't had an MMA fight since defeating Eddie Alvarez at UFC 205 in 2016 -- but he's booked to make his triumphant return to the Octagon at UFC 229 on Oct. 6.
Some people are worried Conor could have "ring rust" -- but when you're looking at the new highlight video, he seems sharp and strong.
Obviously, it's heavily edited -- but we all know what Conor's capable of ... and it's cool to see him back in beast mode.
As for Khabib, that dude is an absolute monster -- he's 26-0 and beat the dog snot out of just about everyone he's faced.
The two have bad blood -- remember, when Conor attacked that bus at Barclay's Center back in April, he was gunning for Khabib ... who had disrespected one of Conor's training partners earlier that week.
