According to Eddie Hearn, who promotes British middleweight champion Chris Eubank Jr. (23-1, 18KOs), a victory over WBC/IBO/WBA/IBF middleweight champion Gennady 'GGG' Golovkin (35-0, 32KOs) would be bigger than Ricky Hatton's huge victory over Hall of Famer Kostya Tszyu.

Eubank was in action last Saturday night when he stopped previously undefeated Tom Doran (17-1, 7KOs) in the fourth round.  Doran went down four times in the contest.

Hearn is negotiating a deal with Golovkin's promoter, Tom Loeffler of K2 Promotions, and he believes a deal could be reached as early as the end of this weekend.

The venue of choice is the O2 Arena in London. HBO would carry the fight in the United States and the date would fall in late August or at some point in September.

Hearn says when Hatton fought Tszyu, the Aussie legend was at the end of his career and the fight with Hatton was the final time he stepped into the ring - while Golovkin is in his prime, knocked out his last 22 opponents and is considered to be one of the top pound-for-pound fighters in the sport. Golovkin is also better known and a bigger star in the United States than Tszyu ever was.

"With all due respect to Kostya Tszyu, he was at the back end of his career when he fought Ricky Hatton [in Manchester in 2005] and it was his last fight," Hearn said to Nick Parkinson.

"But Golovkin is bang in his prime, there has never been a worse time to fight GGG than now. I don't think there's ever been a fighter of his magnitude to come to the UK, ever."

Eubank Jr. will reportedly earn £3 million [nearly 4 million USD] from fighting Golovkin.
