Logan Paul has taken perhaps the bold step of claiming that KSI hits harder than all-time great welterweight Floyd Mayweather.
The YouTuber-turned-boxer has been in the ring with both men. He fought KSI in two matches - the pair drawing in Manchester in an amateur match in November 2018, before a rematch under professional rules in LA a year later saw KSI take a split decision.
He fought Mayweather, meanwhile, in a highly publicised exhibition bout earlier this year that went to draw - although many thought the five-division World Champion and previously retired Mayweather was operating well within himself.
Nevertheless, sitting down with True Geordie (real name Brian Davis) for an interview, Paul claimed it was KSI who he found the harder hitter.
Asked by Davis who hit harder, he replied: "KSI for sure, for sure, not even a competition.
"Mayweather has clean shots, and I was like cool, good job. KSI, I was like keep me away from those hands."
The question during an interview where Brian and Logan re-watched the Mayweather vs Paul fight and offered their own analysis.
Elsewhere in the chat, Paul reflected on his journey into the boxing world and the fight itself.
He said: "It's a lot to take in, I got humbled then I took up boxing and it changed my life.
"It is hard to put in to words, I have been through so much s***, to go from one of the most hated people on the planet to the Mayweather fight it was amazing.
"The journey was insane, it's my first time watching it as it is so much to process and download, I was proud of the fight, but I had to pat myself on the back and be proud of what happened.
"For me this fight was everything, it has set me up for the rest of my life and this was a huge chapter."
His brother, meanwhile, has been calling out Tyson Fury's brother Tommy Fury in recent weeks, keen to further his own boxing record which currently stands at four wins and no defeats.
Most recently, the younger Paul trolled a video of Fury with his top off in a nightclub which had gone viral.
Fury seemingly had a good night in a club in Liverpool recently after he was seen whipping off his top and beating his chest.
Footage of his Wolf of Wall Street-like antics went viral and of course, the video made its way to his YouTuber rival Jake Paul, who took the opportunity to have a dig at him.
In a video shared on TikTok, Paul can be seen watching the video before holding up a sign which reads: "Date Molly Don't Take Molly."
The first Molly he's referencing there is Fury's girlfriend Molly-Mae Hague, while the second Molly in his sign is meant as a slang word for ecstasy.
Fury has a 7-0 record so far and would likely be a step up from Paul's previous opponents, most of whom have come out of retirement for their fights.
