Jake Paul called out super-middleweight champion Canelo Alvarez after he knocked out Ryan Bourland.
Paul moved his professional record to 9-1 after producing an explosive finish against Bourland in Puerto Rico.
Bourland went into the fight with a 17-2 professional record but the 35-year-old was overpowered by Paul.
After the win, the YouTuber turned boxer said he wants to fight Alvarez.
"I mean, he was supposed to give it to me, right? This guy has 19 fights, he's super-experienced,” said Paul to DAZN. “I guess we've got to step it up way more.
“But I'm ready. I'm getting sharp. This is my life now, and, like I said, I'm on the road to becoming a world champion.
“Canelo, stop ducking. I know you want it. I'm repping Puerto Rico, you're repping Mexico, so it's Puerto Rico vs Mexico. I want Canelo. I want all the biggest names.
“Like I said, I'm the face of this sport. Truly, who's doing more for boxing than me? I keep on proving myself time and time again.”
Amanda Serrano’s title defence was called off at the last minute after she was prevented from fighting because of an eye injury.
Serrano was to defend her IBF, WBA, and WBO women's featherweight titles against Germany's Nina Meinke.
