Gennady Golovkin wants to be paid what he feels he deserves – and not just from DAZN or Al Haymon.

According to a story posted Thursday by theblast.com, Golovkin has filed a lawsuit against his former managers, brothers Maximilian and Oleg Hermann. The ex-middleweight champion from Kazakhstan claims in the suit that the Hermann brothers took advantage of him for many years by intentionally failing to account for revenue from his fights, taking higher percentages in commissions than they were entitled to accept and failing to work on his behalf for his most recent fights.

Golovkin seeks $3.5 million in damages from them. He also wants to terminate the professional partnership.

The 36-year-old Golovkin (38-1-1, 34 KOs) is believed to have earned nearly $25 million from his middleweight championship rematch with Canelo Alvarez (51-1-2, 35 KOs). Golovkin lost a debatable majority decision in that 12-rounder September 15 at T-Mobile Arena in Las Vegas.

Golovkin could fight Alvarez a third time later this year if he opts to sign with DAZN, the fledgling streaming service that signed Alvarez in October to a five-year, 11-fight contract that could become worth $365 million.

Sources have informed BoxingScene.com that the deal offered by DAZN president John Skipper includes at least two fights.

The second fight of that deal would be a September bout against Alvarez, if the Mexican superstar can defeat Daniel Jacobs (35-2, 29 KOs) on May 4 in Las Vegas. If he chooses DAZN, Golovkin likely will partake in the equivalent of a tune-up fight at some point in the spring.

Haymon, the influential adviser that founded Premier Boxing Champions, also has tried hard to secure Golovkin’s services. He, too, has offered Golovkin a multi-fight deal that would begin with a nondescript fight against an undetermined opponent.

If Golovkin were to sign with Haymon’s PBC and win that fight, he would then face Jermall Charlo in the second bout of that agreement. Charlo (28-0, 21 KOs) owns the WBC’s interim middleweight title and once was Golovkin’s mandatory challenger for the WBC 160-pound title he lost to Alvarez.
