UFC’s current household name Conor McGregor swears to beat the undefeated boxing icon Floyd Mayweather Jr. if a rematch will be granted.

In a recent interview with Tony Robbins, UFC’s former two-division champion Conor McGregor spoke thoroughly about his thirst for a boxing rematch bout against Floyd Mayweather Jr. "I would like to rematch him under boxing rules, again...and I believe I would win," he said.

The world has witnessed how the UFC star suffered a flurry of punches from Mayweather during their clash back in 2017, but despite losing, McGregor seems to be confident, as always, that he will now be able to outbox Mayweather Jr. under the boxing champ’s own comfort zone and boxing rules.

McGregor, being the flamboyant fighter he is, even added: "Actually, there I go again with that fake humbleness ... I KNOW I WOULD WIN," TMZ Sports reported.

On a more professional standpoint, McGregor also talked about how he thinks about the fighting style of Mayweather. This time, Mystic Mac went from ostentatious to confident but technical.

“Floyd is known for his Philly-shell defensive style of fighting. He has his right arm tucked in, or he’s orthodox so it’s the opposite, but he has one arm tucked in by his belly and one arm kept up by his ear. He uses his shoulder to deflect shots. He’s a back footed fighter, he fights on the back foot," McGregor said, MMA Mania noted.

Of course, McGregor’s case won’t go unnoticed. Just a few days ago, Mayweather CEO Leonard Ellerbe fired back at the UFC champ and confidently stating that his boss, Floyd, will be more than happy to give McGregor another shot inside the boxing ring.

Ellerbe made sure that his response will match the arrogance of McGregor, saying: “That’s interesting. I hadn’t heard that but Conor McGregor knows he’s always welcome to that ass-whooping.”

After the harsh response, Ellerbe became quite serious and stated that there is only one thing that can prevent the rematch from happening, and that is UFC President Dana White.

Ellerbe emphasized that and sent another message for McGregor.

“All he’s got to do is call Dana. That’s all he has to do. I can’t speak for Floyd but I’ll tell you what, Conor McGregor, if he wants that ass-whooping again, I’m sure Floyd would oblige to that,” he said, MMA Fighting reported.

Mayweather is expected to express his thoughts regarding this matter anytime soon.
