New WBU cruiserweight champion Enzo Maccarinelli says he will use his belt as a stepping stone to the top.
The 22-year-old Swansea puncher stunned veteran Bruce Scott by recovering from a first-round knock-down to KO his opponent with a spectacular combination in the fourth.
Maccarinelli will not kid himself as to the value of the lightly regarded WBU title, but he says he is ready to take on all challengers.
"I'm not calling myself 'the' world champion yet, this is a stepping stone," the fighter told BBC Wales Sport.
"But I'm recognised now and if anyone, anyone wants to try to come and get my title then I'm ready for it."
The first-round knock-down inflicted by Scott had ringside observers waiting for Maccarinelli to fold, as he had on his other big TV night against Lee Swaby three years ago.
The Swansea scrapper - who has still never been beyond four rounds as a professional - admitted to early jitters when faced by the chunky, intimidating Scott.
"It was a nervy start and I got caught by a left, but I didn't panic," he said, "My head cleared straight away and I was able to get him on the end of my jab.

Jimmy Wilde (World flyweight champion, 1916-23)
Howard Winstone (WBC featherweight champion, 1968)
Steve Robinson (WBO featherweight champion, 1993-95)
Robbie Regan (IBF flyweight champion, 1995, WBO bantamweight champion, 1996)

"I kept getting to him with my right, then in the fourth I threw a combination and he rolled onto my left.
"Every time I caught him I hurt him - I'm ready to box anyone."
Although most would argue over the validity of the WBU crown, Maccarinelli's achievement makes him the first world champion from Swansea, and just the ninth to come out of Wales.
Boxing pundit Nicky Piper is one who believes that the Italian-Welshman can go on to back up that claim with more widely recognised belts.
"He's got tremendous, world-class power," Piper told BBC Wales Sport, "He'll be a star of the future."
