Conor McGregor has welcomed high praise from Mike Tyson and promised on his life he will "crack the puzzle" to win an "inevitable rematch" with Floyd Mayweather Jr.
Heavyweight great Tyson, who recently revealed he was coming out of retirement, talked up UFC star McGregor's showing when he was beaten by the legendary Mayweather in his professional boxing debut in 2017.
The former world champion said in the latest edition of his Hotboxin' with Mike Tyson podcast: "He [McGregor] never really had a boxing match in his life, right?
"He went 10 rounds with the greatest fighter in the last 100 years of boxing. He went 10 rounds, scored punches on the greatest fighter in the last 100 years.
"Did he do something? Did he accomplish something? People should look who he had the fight against and look what he did when he fought against him."
Mayweather, who quit with a perfect 50-0 record, says he has no interest in boxing again but is open to the idea of more fights that give him a chance to "entertain and have a little fun".
McGregor expressed his gratitude to Tyson and vowed to gain revenge in a second fight with Mayweather that he believes is bound to happen.
He tweeted: "Thank you Mike, and just know that for the inevitable rematch, with the knowledge I now hold of Floyd's style, plus under the tutelage of my old school boxing coach, I will crack the puzzle, and I will beat Floyd.
"I promise my life on it. It is great to see you back Iron Mike."
