KSI is out to gain revenge against Floyd Mayweather for how the boxing legend treated his younger brother Deji.
Mayweather faced YouTuber Deji in a shock exhibition bout in Dubai in 2022.
But the American icon was accused of forcing Deji into boxing in smaller 10oz gloves on the night of the bout – opposed to a bigger 14oz pair.
It was also claimed Mayweather refused to take it easy on his inexperienced opponent despite a verbal agreement to do so.
Older brother KSI is still seething with the Hall of Fame great and wants to settle it in the ring.
His trainer Alexis Demetriades told SunSport: “There’s a personal thing there with Deji, JJ’s upset with Mayweather. There’s a personal thing.
“They changed the gloves from 14s to 10s on the night, they gave him danger money, they paid him to do it.
“And one of Mayweather’s camp came up to Deji and said, ‘If it gets a little bit hot and you’re in the clinch just tell Floyd to calm down a little bit because it’s an exhibition and he’ll be with you.
“At one point, Deji was like, ‘S***, it’s getting a little bit hot.’ And Mayweather was like, ‘F*** you. I’m Floyd Mayweather’, and tried to kill him.’
“That’s JJ’s little brother. So there’s animosity there, there’s an appetite for that fight for JJ, he thinks he’s a p***k.”
Mayweather, 47, officially retired in 2017 after beating ex-UFC champion Conor McGregor, 35.
But he has continued to box in exhibitions since against stars of the social media, MMA and boxing world.
Among those have been YouTuber Logan Paul, 29, and KSI’s brother Deji, 27.
But coach Demetriades insisted KSI, 31, is not interested in an exhibition against Mayweather and instead wants redemption.
Demetriades said: “He’s going to try and kill him. There’s animosity there. It’s on sight. Like JJ wants to kill him. That’s a fight he wants.
“It’s nuts, it’s crazy to say though, isn’t it? You’ve got a YouTuber that wants to fight Floyd Mayweather.”
Mayweather returns on August 24 in Mexico against John Gotti III -grandson of the notorious mob boss.
