As was expected heading into their awaited showdown at December 12’s UFC 194, featherweight champion Jose Aldo and interim featherweight champ Conor McGregor got into an intense and almost violent staredown at today’s UFC ‘GO BIG’ presser from Las Vegas.

McGregor spent a good portion of the presser dominating most of the talk with his brash and brutal yet creative callouts, especially those focused on his Brazilian enemy. With tension mounting from months of unsatisifaction due to Aldo’s withdrawal from July’s UFC 189, emotions came out and tempers flared when the ‘Notorious’ nearly headbutted ‘Junior’ when they faced off.
