KSI: "It'll be good. They'll be a lot of people watching. I know they'll be more people watching our spar than Jake's fight. Speed is a random guy, he just does wants he wants. You don't know what to expect with him, if he wants to get in the ring then he can. It would be sick to have Speed fighting, it's all on him. I mean, it's a boxing match so you can only punch. I've seen his speed and I know he is fast."
IShowSpeed: "You all don't know how I can fight. You all don't know what these hands can do. I don't care if he's Nigerian, I'm going to prove everybody wrong. I'm beating his a*** bro. I'm literally going to f*** KSI up. I'm going to beat the f*** out of KSI. He can't f*** with me and you all know that."
