Gennady Golovkin feels Saturday's middleweight unification bout against David Lemieux in New York will be like a "street fight".
Golovkin puts his WBA, IBO and WBC titles up against Lemiuex's IBF strap at Madison Square Garden, where he will bid to maintain his unbeaten 33-match record.
The 33-year-old Kazakhstani fighter has knocked out his past 20 opponents and his 91 percent knockout percentage is the highest in the history of the middleweight division.
Lemieux has only been beaten twice – both losses coming in 2011 – and Golovkin feels his style will lead to a brawl of a contest at the Garden.
"This is going to be like a street fight," he said. "He has a good style – almost like an amateur style. I will beat any style – amateur style or brawl style. He will be a good test for me.
"Lemieux is a champion and he feels like a champion and this is a unification fight. I think he is ready for a unification fight and he understands the situation. He is smarter now because of his experience in his recent fights.
"Right now he feels better because he has a stronger team. He gets to talk with Oscar [De La Hoya] and Bernard [Hopkins]. Bernard tells him, I remember my fight at Madison Square Garden against Tito. Right now he is acting like a star – I see the videos – and, of course, he is a star.
"I think this fight is more technical for me, and maybe for him too.
"It is very interesting for me because right now he is a star. With power alone, he could go maybe three or four rounds with me. If he boxes he could go twelve rounds. Every second is very important – every round – every step."
When asked if his next fight would be against Miguel Cotto, who is ranked second in the world at middleweight, or Saul 'Canelo' Alvarez, who is top of the super welterweight rankings, Golovkin said: "It doesn't matter and I don't think about it.
"For me? Whoever is number one. I want all of the belts in the middleweight division and I will fight whoever is number one and it doesn't matter who it is. I don't like the business. I like old school – who is number one?"
