Former undisputed UFC lightweight and featherweight champion, Conor McGregor unleashed an expletive-filled tirade on his official Twitter account overnight – taking aim at five prominent mixed martial arts head coaches, and claiming himself and his head coach, John Kavanagh of Straight Blast Gym, had created a system to defeat the likes of past-foe, Khabib Nurmagomedov.
McGregor, a former undisputed lightweight and featherweight champion, is expected to return to welterweight waters in his UFC comeback later this year.
Finishing filming on The Ultimate Fighter 31 earlier this month, McGregor featured as an opposing head coach on the reality television show against the #5 ranked challenger, Michael Chandler – with the duo expected to fight later this year under the UFC banner.
