Conor Benn wants to fight Yordenis Ugas next after knocking out Chris Algieiri on Saturday night.
Ugas is the WBA (super) welterweight champion and most recently defeated Manny Pacquiao, and Benn had been planning a 2022 title shot even before his fourth-round demolition of the former champion Algieri.
Speaking to DAZN, Benn said: "I silenced all them doubters. Watch the next fight, it's gonna be a fight.
"When I say I'm top five, I'm top five for a reason. No one did that to [Chris] Algieri. What more do I have to do? Maybe I just frustrate myself.
"I'm a top world level athlete. You don't get the rankings I have for nothing. I didn't expect nothing else. I work extremely hard, I knew the KO was coming, if they want to come and have a fight that is what happens.
"I hope the Yanks know I'm the best fighter in Britain, number one, and number two, I'm coming for them."
Benn told the BBC that he wanted Ugas next.
"If Eddie brought me Ugas now I'd fight him. I'm a different fighter now, I'll be even better next fight, I'm always growing, always learning,” he claimed.
"I'm top five. I'm definitely the best fighter in Britain."
