Conor McGregor vs Chad Mendes at UFC 189: A defining moment in McGregor's rise

Conor McGregor vs Chad Mendes at UFC 189 remains one of the defining fights of McGregor's rise. With José Aldo forced out through injury, Mendes stepped in on short notice and immediately showed why his wrestling was dangerous, taking McGregor down and controlling key moments. McGregor kept working, created space and continued attacking on the feet. As the second round approached its end he found the opening and stopped Mendes with punches at 4:57, claiming the interim featherweight championship. The victory set up the historic undisputed title fight with Aldo later that year. Confidence, pressure and finishing ability on full display.
