Paul, who is 4-0 as a professional boxer, will take on Tommy Fury (7-0) in Florida on 18 December, and the latter’s half-brother Tyson is helping to train his sibling for the fight.
“I’ve been terrorising Jake on his inboxes,” Fury told iFL TV.
“They think they’re little talkers, [Jake and brother Logan], but welcome to my world.
“I rule the talking world, me. Not pretend videos and stuff, actually like rule it.”
Fury and his father John accompanied Tommy during Wednesday’s pre-fight press conference, which Paul attended via video call.
Insults were exchanged throughout the chaotic event, but Fury is confident that Tommy will be composed on fight night.
“I know how good Tommy is,” the 33-year-old said. “I’ve seen him knock people spark out in the gym every day. He’s a real banger.
“And when gets one shot on Paul, he’ll be kissing the canvas. Goodnight Vienna. Bye, bye.
“I want a big, old, dirty knockout like Tommy keeps talking about.”
