Anticipation is building ahead of the main event for MF & DAZN: X Series 10 where KSI takes on Tommy Fury in the main event.
For KSI, this is the first time in his crossover boxing career that he will be taking on a professional boxer and some are worried about whether Fury's superior ability and size could be a problem for the YouTuber.
One of those is renowned combat sports journalist Ariel Helwani, who is concerned that Fury's larger frame could be a major problem for KSI.
"We just saw a couple of weeks ago in Las Vegas, Canelo Alvarez against [Jermell] Charlo, I’m obviously not going to compare it in terms of the skill but look at Charlo. Typically, when you have to beef up, you’re losing a lot. I’m just worried about the size," Helwani told DAZN.
"I think KSI is quicker than Tommy Fury, I think a lot of people don’t give KSI the respect he deserves when it comes to how far he’s come.
"With Tommy Fury, we saw what he did against Jake Paul, if he sticks to a game plan given his history, his skills, his upbringing, he just has those intangibles which these newer boxers don’t have."
