internet superstar have been going at it for MONTHS on social media … with Tommy’s 2-time heavyweight champ older bro, Tyson igniting the feud by mentioning Paul on Twitter.

Now that Jake whooped Ben Askren’s ass last weekend, we spoke with Fury about the possibility of being next … and he’s ready to put him in his place.

“I’m here and I’m ready and I’m going to fight, but obviously, this man is not,” Fury tells us … adding he had ZERO interest in getting involved until Jake called him out for clout.

“In the boxing world, he’s a nobody and he’s just trying to use the Fury name — the best fighter in the world is Tyson — to try and get the boxing audience talking about him.”

FYI, Fury is a monster in the ring — he’s 5-0 with 4 knockouts … and would easily be Paul’s toughest matchup to date.

Fury says he’s down to fight Paul “anytime, anyplace, anywhere” … and might get his wish — Jake recently said he would fight Tommy if Tyson boxed Michael Hunter on the same card.

Fury has a better idea — fighting both Jake and his older brother, Logan, on the same night!!
