That's Tommy Fury with a very ominous warning for The Problem Child ... just 3 weeks before their highly anticipated February 26th boxing match in Saudi Arabia.

Of course, the men have been scheduled to fight two other times (more on that later) ... and the bad blood is so real, 23-year-old Fury says he's never wanted anything as badly as he wants a win over 26-year-old Paul.

"This is all that's been in my mind for the past two and a half, three years because I'm a professional, legitimate fighter, and my name has been lingering with Jake Paul for quite some time now and Jake Paul is not on my level," Tommy told Babcock on the "TMZ Sports" TV show (airs weekdays on FS1).

"Jake Paul is not even considered a legitimate fighter and to have my name dragged through the mud with his, I want to prove a point."

Fury continued ... "In three weeks, I get my chance. I don't wanna take it both hands, I wanna school this man. I'm gonna take him to the trenches and he will be drowned. There's no way he can last eight rounds in the ring with me."

Tommy says he's going to put Jake down, and he's going to do it early.

"I see me putting him away early, the way I'm punching in the gym, what I'm doing to people in the gym," Fury said, adding, "There's no way. When the shots land, he will be going down. He will not get up."

Babcock asked Tommy what he'd say to all the people who believe he will find a way out of the fight with Jake.

"I say to those people they need to wake up. Don't worry. I'll be in Saudi Arabia ready for February 26th. I'm ready to go now. I can't wait to get on this plane and get over there."

"I'm gonna hurt this man seriously come February 26th and if he banking on me for not showing, well if that's where he getting his confidence from, then he needs to think again 'cause I'll be there and I'll be right in his face come fight night."

We also talked to former UFC star turned BKFC boxer, "Platinum" Mike Perry ... who Paul has tapped as the replacement fighter, should Tommy fail to make it to fight night.
