Olajide Olatunji, also know as 'KSI', made his professional boxing debut in November of last year against fellow outspoken YouTuber Logan Paul.
The bout - which happened at the Staples Center in Los Angeles and was promoted by Eddie Hearn - was a rematch of their first fight which ended in a majority draw.
And in their second showdown, KSI was handed the split decision victory over his trash-talking American rival.
Now, though, it appears he has set his sights on a far tougher opponent.

According to KSI himself, he reckons he could come out on top against former heavyweight champion Mike Tyson if the two were to face off in a ring.
If you follow the "Baddest Man on the Planet" on social media, you'll see that he's been training hard for a long-awaited comeback fight against Roy Jones Jnr.

"I actually could though, I actually could," KSI said when asked during a YouTube video if he could beat Tyson.
"I'm undefeated, no-one has beaten me."
Well, you can't knock the kid's confidence.
As for Tyson, he's set to slug it out with former champ Jones Jnr in an eight-round exhibition bout in California - although the fight has already been postponed.
