Conor McGregor is the biggest star mixed martial arts has produced, and his Dublin press conference remains legendary chaos. Ahead of his UFC 189 title fight against Jose Aldo, the eight-city world tour stopped in Dublin in 2015, where roughly 3,000 Irish fans turned the venue into a football terrace, breaking into the chant Jose, are you listening, keep that belt glistening while McGregor conducted the crowd like a concert. Aldo stood frozen and unmoved throughout, while Dana White later admitted he'd never seen anything like it in the sport. McGregor went on to knock Aldo out in a record-breaking 13 seconds that December. Known for explosive left-hand power and relentless charisma, McGregor's ferocious fan energy remains one of combat sports' most iconic moments.
Few moments in combat sports history have matched the raw electricity of Conor McGregor's homecoming press conference in Dublin during the UFC 189 world tour in 2015, a stop that turned a formal promotional event into something closer to a rock concert.
Roughly 3,000 Irish fans packed the venue and transformed it into a football terrace, breaking into the now-legendary chant — "Jose, are you listening, keep that belt glistening" — while McGregor stood at the podium and conducted the crowd like a conductor leading an orchestra. UFC president Dana White later admitted he had never witnessed anything like it in the sport's history.
McGregor, known as "The Notorious," was 26 at the time and already the most electrifying presence the sport had seen. Now 38 and fighting out of SBG Ireland, the southpaw stands five-foot-nine with a 74-inch reach and carries a career record of 22 wins and 7 losses. His striking numbers reflect the ferocity his fans adore — he lands 5.27 significant strikes per minute at 49 percent accuracy, among the most productive outputs in the featherweight and lightweight divisions.
Standing across from him at that press conference was Jose Aldo, the reigning champion, who remained frozen and visibly unmoved as the chaos raged around him. The Brazilian, now 40, owns a record of 32 wins and 10 losses and built his legacy on sharp, relentless output — 3.65 significant strikes per minute with 46 percent accuracy over a long and decorated career with Nova Uniao.
The theater of that Dublin afternoon set the stage for one of the most stunning finishes the Octagon has ever seen. When the two finally met at UFC 189 in December of that year, McGregor needed just 13 seconds to stop Aldo with a left hand, setting a record for the fastest finish in a UFC title fight that still stands.
Why it matters
- The Dublin press conference cemented McGregor's ability to weaponize crowd energy as part of his fight preparation
- Aldo's composed silence became its own talking point, illustrating the psychological warfare both men brought to the buildup
- The 13-second finish that followed remains the benchmark against which explosive UFC title moments are measured
