Multiple-time WWE world champion Brock Lesnar and UFC superstar Conor McGregor have found a massive amount of success in the world of Mixed Martial Arts. Both Lesnar and McGregor have established their place as household names in the MMA world, but it wasn't too long ago that the former UFC heavyweight champion put the Irishman on notice.

In an interview with Sam Roberts, Lesnar went off on McGregor. The former WWE Champion started by saying that he takes bigger "sh*ts" than the Irishman, whom he referred to as a "kid".

"I take sh*ts bigger than that kid. Come on. I know you kids all play f****g video games and you live in this f*****g false sense of reality and sh*t. I'm two hundred and f*****g ninety pounds."

Lesnar further continued his rant towards McGregor, stating that the latter was 145-pounds and dared The Notorious One to come face-to-face with him. The former WWE Universal Champion concluded his statement by boasting that he had already found success in the UFC.

"This guy's a hundred and forty-five pounds, if he's lucky. If Conor McGregor wants to say some sh*t to me, and get his name out there more than he already has, by dropping my name, I got about ten f*****g words for him. Come here, face-to-face, Conor, and say it to my face. Otherwise leave me and the f*****g WWE out of it, because I came to your arena and kicked a**." Said Lesnar.

Lesnar expressed his frustrations mostly due to the fact that McGregor initially spoke ill about WWE and the superstars of the company a few years ago.
