McGregor knocked out Alvarez at UFC 205 in November 2016 to make history as the first-ever simultaneous two-division UFC champion. Meanwhile, two days before that bout, 'The Notorious' had an unforgettable exchange with Stephens at a press conference, where he famously remarked, "Who the f**k is that guy?"—a line that would become one of his signature catchphrases.
