Jake Paul just went toe-to-toe with former UFC champion Anderson Silva -- and WON -- coming away with his hand raised in an incredibly impressive bout on Saturday.
The Problem Child and Spider beat each other up for eight rounds ... but neither fighter could finish with a knockout.
Jake, however, had the lone knockdown of the fight in the 8th round ... after a short right to Silva's head.
Paul got the dub via unanimous decision in Phoenix ... and now the former YouTuber-turned-superstar says he wants to go up against Canelo Alvarez or Nate Diaz.
