Michael Chandler vs. Khabib Nurmagomedov?!?!
It's not completely out of the question, according to Chandler who tells TMZ Sports he wouldn't be surprised if Khabib eventually changed his mind about the whole retirement thing.
Chandler is currently set to fight Charles Oliveira at UFC 262 on May 15 for the vacant UFC lightweight belt ... but he's EXTREMELY confident he'll smash his way to the title -- which begs the question, who's next!?
Maybe ... but Khabib is only 32 years old and still VERY involved in MMA, coaching stars like Luke Rockhold and recently serving as a cornerman for his brother Abubakar Nurmagomedov at UFC 260.
