Eddie Hearn is seemingly growing impatient with Gennadiy Golovkin.

Hearn, whose company co-promotes Golovkin, expressed exasperation Saturday night with Golovkin’s plan to return to the ring December 31 against Ryota Murata. According to Hearn, Golovkin, the IBF/IBO middleweight champion, intends to meet Murata, the WBA champ, on New Year’s Eve in Japan, Murata’s home country.

Hearn believes Golovkin should face Demetrius Andrade in another title unification fight sometime this summer. The British promoter discussed the Golovkin-Andrade scenario with DAZN’s Chris Mannix after Andrade (30-0, 18 KOs) recorded a 12-round, unanimous-decision defeat of WBO mandatory challenger Liam Williams (23-3-1, 18 KOs) on Saturday night at Seminole Hard Rock Hotel & Casino in Hollywood, Florida.

“If I’m Gennadiy Golovkin or I’m Jermall Charlo,” Hearn said, “I’m looking at [Andrade] and going, ‘I can beat him.’ So, why not step up? Gennadiy Golovkin, a great champion, you know, he’s planning a fight with Murata on December the 31st. We’re in April. Gennadiy Golovkin should be looking and speaking to DAZN and us and saying, ‘I’ll fight Demetrius Andrade in the summer and then I’ll fight Murata in Japan.’ Two massive unification fights.

“Champions have to fight champions. And Demetrius can’t just keep defending his belt. He was great tonight. Liam Williams was great tonight. And again, like you said, [Andrade] was hurt, he was tired. He can’t make 160 forever. So, if you’re Charlo, if you’re Golovkin, let’s do it. Let’s make the unification fights. Champions v. champions. That’s what boxing’s about.”

The 39-year-old Golovkin pummeled Poland’s Kamil Szeremeta in his most recent fight, a mandatory defense of his IBF belt December 18 at Seminole Hard Rock Hotel & Casino. Golovkin knocked the overmatched Szeremeta (21-1, 5 KOs) to the canvas four times – once apiece in the first, second, fourth and seventh rounds – before their scheduled 12-round bout was stopped following the seventh round.

Kazakhstan’s Golovkin (41-1-1, 36 KOs) remains hopeful that he can land an elusive third fight against rival Canelo Alvarez.

Mexico’s Alvarez is preoccupied, however, with becoming boxing’s fully unified super middleweight champion. Alvarez (55-1-2, 37 KOs), the WBA and WBC 168-pound champ, is scheduled to battle WBO champ Billy Joe Saunders (30-0, 14 KOs) on May 8 at AT&T Stadium in Arlington, Texas.

If Alvarez defeats England’s Saunders, he is expected to pursue a September showdown with unbeaten IBF champ Caleb Plant (21-0, 12 KOs).

Murata, meanwhile, has long been mentioned as a potential opponent for Golovkin.

Bob Arum, Murata’s co-promoter, has repeatedly predicted a Murata-Golovkin fight could draw a capacity crowd of nearly 60,000 to Tokyo Dome. The 35-year-old Murata (16-2, 13 KOs), a 2012 Olympic gold medalist, is a mainstream star in Japan.
