O'Malley is ready to oust McGregor.

Sean O'Malley, the UFC lightweight champion, believes he is ready to dethrone Conor McGregor from the pedestal of the promotion's top star.

"I'm close to McGregor's star power. Conor still has one huge fight and that's a big question mark. Will he be able to come back? Can he beat Michael Chandler? I think he has one more big fight in store, and if he goes out and loses it, it'll be a sixth straight loss, something like that. His star power will fade and I'll be the number one superstar. I'm going to be that guy."
