Conor McGregor will be remembered as one of the biggest mixed martial arts stars of all time, but one of his greatest rivals says he's heading down a dark path - one that can be altered if the former two-division champion is willing to change.

UFC legend Khabib Nurmagomedov is of the belief that his long time rival Conor McGregor is still capable of changing his ways.

Conor McGregor's friend believes his party lifestyle cost him the Khabib fight, claiming more training could’ve led to victory.
