Chargin, who currently advises Golovkin’s main rival Canelo Alvarez, is involved in preparations for the Mexican’s bid to win a third world title when he battles Liam Smith a week later.
Talks between Golovkin and Canelo for a WBC stipulated clash this year broke down when Alvarez ruled himself out due to still being able to make weight at 154 pounds.
The pair now go their separate ways, but are massive favorites in their respective fights and Chargin says he can’t envisage any fighter who could stop the Golovkin juggernaut from claiming yet another victory.
“I don’t think anyone can beat Golovkin at this time,” Chargin exclusively told World Boxing News.
“Nobody will be ashamed of Brook’s performance, though, including the UK fans and the fighter himself, but I would bet that it won’t go the distance if I were a betting man.
“On the other hand, I wouldn’t be shocked if it goes the limit as Brook is a tough fighter, and which is why I’m not a betting man.”
Asked whether Canelo could follow Golovkin’s lead and book a massive encounter on UK soil in the future, Chargin said: “I can’t answer that one for Canelo but I’m sure he prefers to fight in the United States.”
All parties involved are hopeful an agreement between Golovkin and Canelo will happen towards the end of 2017, with the general consensus being the two pound for pound stars won’t have too much trouble in their upcoming contests.
