Conor McGregor believes he will do better if he gets a rematch with Floyd Mayweather Jr. In fact, the Ultimate Fighting Championship superstar is confident that he will defeat the unbeaten boxing icon in a second fight.

McGregor impressed boxing fans in the early rounds of their super fight in August. However, the Irish superstar did not have enough gas left in his tank in the later rounds and Mayweather took advantage en route to a scintillating 10th round knockout win.

The reigning UFC lightweight champion admitted that his inexperience was a big factor during the first fight.

But after their first showdown, McGregor thinks that he now has enough experience to defeat Mayweather.

“I know if I went another go with him, under boxing rules, I’d get that win,” McGregor told MMA Fighting. “I know that. I know by the feeling of him in the first fight.”

McGregor blasts referee for unfair treatment

Meanwhile, McGregor blasted referee Robert Byrd for stopping the fight, which gave Mayweather his 50th win in as many fights. The 29-year-old mixed martial arts superstar told MMA Fighting that he knew all along that Byrd will not give him a fair shake.

McGregor claimed that Byrd was too focused on him, particularly during the time the referee was announcing the rules of the bout.

“The Notorious,” said that the veteran referee did not even look at Mayweather, not giving instructions to the undefeated boxing superstar.

He also pointed out that Byrd was too physical on him when separating him from Mayweather during the fight. McGregor said that Byrd kept on pulling him away, which took a lot of energy from him.

McGregor’s comment came after he was informed that the referee is the husband of boxing judge Adalaide Byrd. The lady judge was handed a temporary suspension because of her controversial 118-110 scorecard for the close Canelo Alvarez-Gennady Golovkin showdown earlier this month.

Will the Mayweather-McGregor rematch happen?

Mayweather, who now owns a 50-0 record with 27 knockouts, has not shown signs of willingness to fight again.

Most analysts believe that Mayweather only fought McGregor to get his 50th victory.

Most fans also believe that Mayweather will not fight McGregor in a rematch or will not return to the boxing ring at all. However, UFC color commentator Joe Rogan said that a rematch is too good to pass up, especially after getting 4.4 million pay-per-view buys, the second-largest in the history of the sport.

“He’s [Floyd Mayweather] probably gonna make more than 300 million dollars from this last fight,” Rogan said on The Joe Rogan Experience Podcast. “Amazing. I can’t imagine that they won’t do it again.”
