The 50-year-old (55-7-2-KO32) held all four world middleweight titles in 2004 before suffering back-to-back defeats to Jermain Taylor but he became WBC world light-heavyweight champion in 2011 when he outpointed Jean Pascal.
He went on to unify the WBA and IBF titles in the same division in April 2014 and despite losing them to Sergey Kovalev via unanimous decision in November, hinted he would be prepared to face the unbeaten Golovkin (33-0-KO30) at a catchweight.
In an interview reported on BoxingScene.com, the American said of the Kazakh: "I was the middleweight terror for 12 years of my career.
"You have guys turning down $2m dollars not to fight this guy. I would have fought him for $50,000 back then, because I wanted to show that I was the best fighter in my weight division.
The only guy out there that nobody wants to fight, that I see, between 160 and 169 is Triple G.
"The only guy out there that nobody wants to fight, that I see, between 160 and 169 is Triple G. Oscar (de la Hoya) called out Triple G, so now they are going 'now Bernard is calling out Triple G' and someone will try to talk me out of it.
"It has to be weight situation on both sides, but it's good to see a middleweight guy Triple G dominating like I was dominating back then.
"But if I was going to fight anybody out there, where I had to be on my A-game, it would be that fight."
Golovkin, 33, stopped Willie Monroe Jr in six rounds in California in May to preserve his status as WBA (super) middleweight champion.
