McGregor has tasted his fair share of success too. He won the Cage Warriors Lightweight Championship while recognised as the Featherweight Champion; a feat he repeated in UFC when he became the first man to hold two titles's simultaneously when he added the Lightweight title to the Featherweight strap he already owned.
McGregor has notched up wins over top names such as Eddie Alvarez, Jose Aldo and Nate Diaz to name but three.
His credentials should never be overlooked. McGregor is one of the sport's greatest.
