It has been 14 months since Conor McGregor stepped foot inside the Octagon, but the "Notorious" one's presence still looms large over the UFC's lightweight division he still champions. Khabib Nurmagomedov doesn't appear to care all too much about these things.

The undefeated Dagestan-born smashing machine addressed the current title picture in the 155-pound fold after his drubbing of Edson Barboza at UFC 219 in Las Vegas this past weekend. In a post-fight interview with UFC analyst Joe Rogan, Nurmagomedov said he'd rather focus on interim titleholder Tony Ferguson because he doesn't believe McGregor has any intention of coming back to fight inside the cage.

Those words must have caught the Irish superstar's attention, as the the former double champ sent out a message on Twitter. Nurmagomedov responded in kind and a solid Twitter beef unfolded.

Truly truly truly get on your fucking knees and beg me. Otherwise I don't give a bollox.

While Nurmagomedov facing Ferguson seems the more likely choice, there's no denying the appeal of a possible matchup between the AKA fighter and McGregor. Both have looked damn near invincible at times, and a matchup between them would be the biggest tilt the UFC could make in the lighter weight classes.
