Adam Azim dismissed the challenge posed to him by mandatory challenger Enock Poulsen.
Poulsen is undefeated and the former super-lightweight champion at European level.
That title is now held by Azim as he retained his own unbeaten record as he defeated Franck Petitjean on Saturday.
Poulsen, the mandatory challenger who had to vacate the belt, has said he is coming for Azim, but the Briton has little time for the Dane.
"He fought Petitjean and he didn't stop him and it was a bit of a closer fight. With me I stopped him and it shows my level as well," he told Sky Sports. "I'm up there at world level.
"I've got the stoppage, it shows him as well that I'm a threat.
"His manager came up to me and said: 'He's the fastest and most powerful guy I've ever fought' and I'm the only guy to stop him in nine years."
He added he had learned lessons from the fight, saying: "What I did wrong was I rushed my stoppage, I tried to get the stoppage so early. I stood my ground. I knew the stoppage was coming, I knew it was probably going to come in nine or 10. I was breaking him down and it was like a big beatdown as well.
"[At the finish] I threw an uppercut and he just went down. I think he felt the power, the speed and he knew it was a beatdown. So it was good.
"I wanted to win it by knockout and I did that."
