Logan Paul Says He Wants To Fight Tommy Fury To Avenge Jake's Loss

If Jake Paul and Tommy Fury don't run it back, there's one guy who's already lining up to be TNT's next boxing opponent ... and it's none other than Logan Paul.

Logan expressed his wishes in a sit-down interview with the Problem Child on the "BS W/ Jake Paul" podcast (recorded the day after the Fury fight) ... and he admitted the result had him wanting to, as their mom put it, "kill that kid."

Logan initially asked Jake what he was planning to do in the ring following the loss ... and he made it clear he wants a rematch with Tyson's little bro.

But if Paul vs. Fury II doesn't work out ... Logan's ready to step in and avenge the family name.

"If you don't [have a rematch], I'd like to handle that," Logan told Jake. "That was like, my first instinct, obviously."

"He's my little brother. F*** that. Inflatable arm ass, motherf***er. F***."

Jake then joked that they could both avenge each other's losses if he were to go up against the Maverick's former nemesis, KSI ... and they could "start an Avenger movie."

But as of right now, it sounds like Tommy will grant Jake a rematch ... and the two will add another installment to their rivalry.

There's more in the interview -- Jake said he predicts the Tommy fight had more than half a MILLION Pay-Per-View buys ... which would explain his claim he made $30 million for one night of work.
