McGregor is starring on the reality show where MMA hopefuls live, train and face each other to win a UFC contract.
And he is going up against Chandler, with the pair then in line to fight at the end of the year.
McGregor has a team full of prospects in the bantamweight and lightweight divisions, with Chandler coaching the veterans.
And in the season opener, Nate Jennerman of Team McGregor was knocked out ex-UFC star Roosevelt Roberts of Team Chandler in 10 SECONDS.
But things only worsened for the Irishman in the next bout when his No1 pick Mando Gutierrez faced Cody Gibson.
A flying knee by Gibson with a just one minute and 36 seconds of the first round remaining left Gutierrez bloodied and beaten.
McGregor, 34, was seen comforting and consoling the devastated prospect in the changing room afterwards.
He said: “Right here with you, Mando. Right here with you my man, we’ll go back to the gym now.”
Talking post-fight, McGregor added: “Mando is a great little fighter, though. I would’ve liked him to stand his ground a bit more.

“He was on the float a little bit too much for my liking. We were working on cutting the octagon in camp.”
Gutierrez said: “I just wanted to give my hear out.”
And McGregor replied: “That’s what you did, man. That’s what you f****g did my man. World champion I’m gonna f****g get you to.”
