Now retired UFC fighter Conor McGregor has claimed that Floyd Mayweather has 'backtracked' on an agreement to fight the Irishman following their first bout two years ago.
Back in August 2017, McGregor and Mayweather fought with strict boxing rules and The Notorious has claimed there was actually supposed to be a follow-up fight set to take place in the Octogan.
However, McGregor appears to be slightly disgruntled that the American boxer has gone back on his word.
"Originally the promise was that I fought him on his terms, and he then fought me on my terms," McGregor told Tony Robbins, as per The Mirror.
"I haven’t heard from him since. We’ll see what happens. I would love another go in the boxing ring, to see what happens.

"I know he’s not going to come into my game, but I would love to rematch him under boxing rules again and have that knowledge and my sparring partners coming forward with that style and see where we go.
"I believe I would win. Actually, there I go again with that fake humbleness. I know I would win."
McGregor has always been an outspoken character but, this time, the Irishman revealed his admiration for Floyd for how he adapted during their last bout.
"Floyd Mayweather is known for his Philly shell defence style of fighting. He has one arm tucked under and another under his chin, he deflects shots with his shoulder," he added
"He's a back footed fighter, and that’s what I prepared for, because that's what I had seen from him.
"Then, when I went into the fight, I was whooping him in the early rounds. I actually went back to my corner after the first round and said ‘this is easy’.
"Then he had to switch up his style, and you’ve got to respect that, he switched to the Mexican boxing style.
"The Mexican boxing style is where you put your elbows in tight and walk forward with heavy pressure. He never fought like that in his entire career."
Following that fight, McGregor's career has taken a bizarre turn. The Notorious famously made a return to the UFC to take on Khabib Nurmagomedov but lost in quite dramatic fashion. Since then, the Irishman has announced his retirement and thanked his fans 'for the cheese'.
Away from fighting, McGregor has launched his brand own brand of whiskey named 'Proper No. Twelve'. Nonetheless, fans across the world aren't necessarily convinced that McGregor, at 30-years-old, has fully stepped away from fighting just yet.
In true WWE fashion and making a shock return from retirement, many feel McGregor will do just that. However, whether that be to fight either Floyd Mayweather or Khabib, that remains to be seen.
