Khabib Nurmagomedov Says Conor McGregor Doesn't Deserve Rematch

Khabib Nurmagomedov has a message for Conor McGregor -- Want a rematch? Get in line.

The UFC superstar touched down in Australia with his crew on Wednesday where he was swarmed by local media and fans.

Khabib was super cool with everyone -- taking selfies and talking with people -- but the headline here is the trash-talk directed at McGregor.

One of the reporters asked if Conor should get the rematch -- to which Khabib smirked and said, "Rematch for what?!"

The reporter brought up all the talking Conor did before their fight at UFC 229 back in October -- Khabib again shot back with an insult.

"Before last fight he talked too. But, when we go inside the cage, he don't do nothing."

Of course, Khabib mauled Conor before McGregor tapped out in the 4th round.

Despite Khabib's position, UFC boss Dana White told TMZ Sports he IS working on the rematch and it should go down in 2019 ... if everything goes according to plan.
