Gennady Golovkin says Kell Brook will become an early knockout victim if he decides to turn their September 10 bout into a 'street fight'.
Brook (36-0-KO25), the reigning IBF welterweight champion, is preparing to challenge fellow undefeated fighter and WBA 'Super', IBF and WBC middleweight champion Golovkin (35-0-KO32) at The O2, live on Sky Sports Box Office.
It will be Brook's first fight at middleweight and the Kazakh knockout specialist has told the Brit that a rash approach will lead to an early end to their fight.
"I know that Kell is a good fighter, but I know my style and I am ready," Golovkin told Sky Sports News HQ.
"I am very interested in what Kell will do. He will not fight like a street fighter because that would be a very short fight. If he is moving and dancing, maybe longer because I know I need time."
He added: "He [Kell] looks good, he is not a small guy. It's very interesting because Eddie Hearn said Kell will have a deal with you, he's already 160lbs. I said 'wow, this is interesting'."
Golovkin is preparing for the fight in Big Bear Lake in California and his trainer Abel Sanchez has warned Brook of the threat posed by the 34-year-old.
"I have worked with a lot of heavyweights who were big, big punchers, but with Gennady, it hurts when he hits you," Sanchez said.
"God gave him heavy hands, I guess the parents had something to do with that.
"But I think at this stage you can improve it and, if you saw him sometimes, he would stop and feel where his balance was. I think technique, timing and speed has a lot to do with it."
