Floyd Mayweather Sr claims he has no idea who KSI is.. despite training YouTuber last year for Logan Paul fight

FLOYD MAYWEATHER SR claims to have no idea who KSI is - despite TRAINING the YouTuber last year for his first Logan Paul fight.

Internet star KSI - real name Olajide Olayinka Williams or "JJ" - beat rival Paul on their professional boxing debuts in Los Angeles last weekend.

But the pair fought to a draw in an exhibition bout last year, and the Brit, 26, spent time in Floyd Jr’s gym in Las Vegas and filmed a session with Mayweather Sr.

In the rematch KSI had Mayweather Sr’s brother Jeff as one of his coaches.

And Jeff checked in on Floyd Jr’s dad and ex-trainer to ask him how he thought KSI had developed from the first bout last year - but Sr had no clue who either YouTuber was.

Jeff asked: "Did you see the fight at the weekend? KSI vs Logan Paul?”

Mayweather Sr replied: “KI... Logan Paul?”

Jeff replied: “You used to train KSI, I know you remember that.

“But still, Logan Paul says he wants to fight you.”

A puzzled Mayweather Sr said: “Who? So what happened? What did he say?”

Jeff revealed Paul called out his brother, and explained: “He said he wants you after that fight?”

But the 67-year-old did not know about the YouTube bout, as he said: “After what fight?”

Jeff replied: “The one he lost at the weekend, to KSI.”

To which Mayweather Sr questioned: “Who is KSI?”

Jeff laughed to the camera, and said: “He trained him, too! And he just can’t remember!”

But not backing down from a challenge, Mayweather Sr said: “Look, man you better stop talking s*** before a mother f***er get knocked out cold.

“Hey if he want it, he can get it! Anyone that want it can get it."
