A user posted it on Twitter saying, "KSI really got 80.000 people screaming ‘F**k Jake Paul’"

'S**t on Jake Paul's entire boxing career'

KSI and Jake Paul are prominent celebrity boxers with successful pay-per-view events and promotions. Paul has won against notable opponents like Anderson Silva and Tyron Woodley, while KSI maintains an undefeated record. However, a fight between the two has not yet materialized, with discussions beginning in 2019 following Williams' split decision victory over Logan Paul, where two referees were in favor of him and one in favor of Logan.

KSI announced his intentions of fighting the younger Paul brother in an interview with Seconds Out along with a plot to potentially damage his opponent's boxing career . He said, "I think Joe Fournier is up there, but I think Tommy Fury is a tougher opponent. That's why, once I destroy Joe Fournier, I'm going to get through to Tommy Fury. Destroy him, and then s**t on Jake Paul's whole boxing career... It's just BS man, he doesn't want [the fight]."
