KSI has refused to rule out a potential collaboration with WWE and called the wrestling promotion his "childhood."
The 26-year-old YouTuber, real name Olajide Olatunji, successfully defeated fellow internet personality Logan Paul in a blockbuster boxing match last month.
And KSI has now shifted his attention away from boxing and teased the idea of making a splash into wrestling.

Speaking to AllHipHop, the internet star has admitted that he could work with either WWE or rival promotion All Elite Wrestling.
He said: "I like doing that type of stuff. Of course, I'm always open to doing WWE, AEW, or whatever organisation there is. I've been a fan for years.
"Man, that's my childhood. I used to watch Stone Cold Steve Austin, The Rock, Hulk Hogan, Sting, Mick Foley/Mankind, The Undertaker, all these guys, Triple H.

"I'm a fan, so it would be a dream come true to fight in the WWE. It'd be a bit too mad for me. I think at that point I'd probably need to check into a hospital just to check that I'm sane."
KSI clashed with Paul in a professional boxing bout at the Staples Center in LA.
And the Brit managed to secure a controversial split decision victory over his fellow YouTuber.
Paul, 24, was furious that he was docked points for illegal back-of-the-head blows when KSI hit the canvas in the fourth round.

KSI mocked the American star after the fight and argued that the defeat would continue to haunt him.
"[Logan] said, 'Oh, look at this, we made history, it's a huge event, biggest ever numbers on DAZN, blah, blah, blah,'" he told No Jumper podcast.
"But I was like, 'You still lost, bro,' and forever, forever and ever he will always be seen as the guy that lost to KSI.

"Imagine that. That f*****g sucks, man, that's why I trained so hard, f*****g hell I trained.
"I pushed myself to the f*****g brink, because I didn't want to, for the rest of my life, be the guy that lost to Logan Paul. Oh my God, man."
