Conor McGregor is known and celebrated as much for his verbal skills and psychological warfare as much as he is for his knockout power and skill within the Octagon.

The Irishman has famously used press opportunities and conferences to get in his opponent’s head before the two competitors have even entered the arena for the bout.

Arguably the best case of McGregor’s use of psychological warfare came against Brazilian José Aldo before their UFC Featherweight Championship unification bout on 12 December 2015.

The video clip recently posted to Twitter by @mmagonewild has reminded us of just how crazy some of McGregor’s actions were in winding up his Brazilian opponent before the fight, which was delayed from the July to December of that year.

The clip recalls the infamous moment that the ‘Notorious’ reached across the press conference table and grabbed Aldo’s featherweight championship belt, lifting it aloft above his own head and declaring himself as “The King”, in response to Aldo having labelled himself with that title moments before.

The bold and shocking move by McGregor is met with wild cheering by the crowd, with the press conference having taken place in McGregor’s home city of Dublin, Ireland.

The clip catches the vocal Irish spectators joining in for a humorous chant of, “Who are ya?” targeted at José Aldo, of course. Dana White, president of the UFC, later commented on the reception that:

“In 15 years, I have never seen any s*** like Dublin”.

Following McGregor’s steal of Aldo’s belt, which the Irishman had also done to Aldo backstage of a press event before, Aldo can be seen extremely distressed by the situation in the clip.

The very unsettled featherweight legend is seen trying to reach across Dana White and appears extremely unimpressed, meanwhile McGregor remains much more comfortable in the situation and laughs in the Brazilian’s face.

Many argue that press conferences for bouts in the fighting sports are often purposely heightened in drama, rivalry and even controversy to sell the fight.

However, it has been proven by the now former UFC featherweight and lightweight champion McGregor that the psychological battle before a bout can be the greatest tool that a fighter can use.

Further clips and insights would reveal how many such bold actions by the unfazed McGregor successfully wound up Aldo, with the then 29-year-old Brazilian claiming:

“I am really mad, I can’t wait to go right through him”. And arguably, it was ultimately this impatience built up in Aldo’s mind that led to the champion’s downfall.

After just a few seconds into the fight, Aldo impatiently charged towards McGregor with a right hand, cueing McGregor to step back and floor Aldo with a sharp left before hammer fisting the fallen champion, causing referee John McCarthy to end the fight and crown Conor McGregor as the new holder of the UFC featherweight title belt. And this time, it was incontestably his belt to hold aloft his own head.
