Virgil Hunter, who trains Andre Ward, Amir Khan, Andre Berto and several other boxers, has continued his criticism of Mexican superstar Saul "Canelo" Alvarez (48-1-1, 34 KOs).

Hunter worked the corner for Khan when he faced Canelo last May at the T-Mobile Arena in Las Vegas. After Khan was knocked out in the sixth round and the fight was over, Hunter dared Canelo to fight middleweight king Gennady Golovkin (36-0, 33 KOs).

Obviously the fight never took place, with Canelo moving down to junior middleweight to capture the WBO world title with a knockout of Liam Smith last September.

Both fighters are set for big HBO Pay-Per-View encounters in the coming months, with Canelo facing Julio Cesar Chavez Jr. on May 6th at the T-Mobile, and Golovkin making a mandatory defense against Daniel Jacobs at Madison Square Garden in New York City.

The big issue in finalizing Canelo-Golovkin for this coming September is the money. Canelo has offered Golovkin a flat fee - while Golovkin wants a reasonable percentage of the revenue. Golovkin reportedly rejected as much as $10 to 15 million.

Hunter agrees with Golovkin's position. He feels Golovkin is a big enough draw, and a big enough name, to receive a percentage.

Several years ago, Manny Pacquiao rejected a flat fee of $40 million to face Floyd Mayweather Jr. At that time, Pacquiao had never made that type of payday for a single fight. Pacquiao stood his ground, and in 2015 - when they finally fought - he walked away with well over $100 million based on a 60-40 percentage split.

Hunter believes Canelo and his team are killing time while waiting for the near 35-year-old fighter to get old.

"I just heard today [Canelo made an offer to Golovkin]... $15 million, you take it or leave it. I think even that is unfair, because you wouldn't make what you're going to make without [Golovkin's] popularity. If he wasn't who he was, you wouldn't be making what you're making. It's a leverage thing right now. It's pretty simple, they are just waiting until he gets old or hope that somebody knocks him off or something like that," Hunter said to Villainfy Media.
