The punches won’t fly until Dec. 19, but Jake Paul and Anthony Joshua are talking.

‘They say I’m unproven,’ Paul says. ‘Untested. That I talk big and fight small. Well, surprise, b—-.’

Joshua, the Brit, says, ‘It’s time for America to see what real power looks like.”

Those words are featured on the fight trailer released by Netflix, which will livestream the eight-round, heavyweight fight, and Most Valuable Promotions, co-founded by Paul.

‘This is the fight that shuts everyone up,’ Paul continues on the trailer.

Says Joshua, ‘This is the fight that shuts men down.’

It’ll be Paul’s biggest challenge yet.

Paul, the former YouTuber, is 12-1 with seven knockouts. Joshua, the former two-time world heavyweight champion, is 28-4 with 25 knockouts.

The co-main will pit undisputed super featherweight world champion Alycia Baumgardner against contender Leila Beaudoin. The main card also includes a bout between retired UFC superstar Anderson Silva and retired former UFC champion Tyron Woodley and a bout between 2021 amateur world champion Jahmal Harvey against prospect Kevin Cervantes, who is 5-0 with five knockouts.
