Youtube star turned boxer, Jake Paul (4-0, 3 KOs), is promising to do a lot of damage when he faces Tommy Fury (7-0, 4 KOs) on December 18th in Miami, Florida.

Their fight will headline a Showtime Pay-Per-View event.

Paul was in action back in August, when he won an eight round decision over former UFC world champion Tyron Woodley. On the same card, Fury won a four round decision in a scrap with combat sports veteran Anthony Taylor.

Fury, the younger brother of WBC heavyweight champion Tyson Fury, is the first pro boxer that Paul will face.

Paul, 24, believes the 22-year-old Fury, is an easier fight than the 39-year-old Woodley.

Fury and his family members are predicting a lopsided win - but Paul expects the exact opposite.

"His whole family is underestimating my ability and how good I am as a boxer. Tommy Fury couldn't do anything to harm my sparring partner Anthony Taylor. All love to Anthony Taylor, but height difference, weight difference," Paul said.

"He didn't do a single thing to Anthony and there were points where Anthony was in control, winning, landing harder punches. So, look what I'm going to do to this guy. It's going to be a massacre, a Boston Tea Party 2.0. I'm taking this motherf----- and throwing him overboard.

"Tommy, he's a great boxer, he's undefeated, he's got fast hands, he's quick, he comes from a legendary bloodline, so long and so forth. I just think that boy will crack under pressure. And I've taken out everyone from the UK. Deji, Joe Weller, Gib, KSI's scared, he's really next up on the list.

"And we see how they are in fights, all of them have cracked, all of them have lost. Once they get on the big stage against me, he's (Fury) going to crack. To answer it, I think Tommy is an easier fight than Tyron for sure. And I think I knock him out, for sure. And I know I said that about Tyron, but that's really the only time I've been wrong. Tyron, he came ready to fight that night and he's been hit by some big guys. Tommy's never even been past four rounds. We'll see what happens."
