Gennady Golovkin could end WBC middleweight champion Saul “Canelo” Alvarez’s boxing career once the two fighters square up in September, according to legendary trainer Nacho Beristain.

Beristain believes the potential megafight of 2016 between Golovkin (34-0, 31 KOs) and Alvarez (46-1-1, 32 KOs) should not push through because the undefeated Kazakh is “much better” than the Mexican champ. Beristain said Alvarez’s boxing skills are not enough to withstand the power of “GGG,” who currently holds the IBF, IBO, and WBA middleweight belts.

“I think he [Golovkin] could destroy [Canelo's] career,” Beristain said, reports Boxing Scene. “Currently, Canelo is the most successful fighter of the world, and he is very important to Mexican boxing. But I think Golovkin may even force him to retire."

Alvarez and Golovkin are set to take on their respective voluntary title defense before their much-awaited match-up. Alvarez has yet to pick an opponent, but according to Dan Ambrose of Boxing News 24, the Mexican red-head is only up for “easy money” fights as he is reportedly considering the likes of Gabriel Rosado and Willie Monroe Jr.

Meanwhile, K2 Promotions have already penciled a definite date and venue for Golovkin’s next bout. The undefeated Kazakh has been linked to fighting WBO middleweight champion Billy Joe Saunders, but the Briton would only agree to terms of a deal if it would involve huge money.

According to Dan Rafael of ESPN, there are also talks going on between Loeffler and Golden Boy Promotions vice president Eric Gomez to have Golovkin fight Tureano Johnson.

"We've had preliminary talks," Gomez said. "It's GGG's mandatory fight and it's a fight we'd like to make."

Johnson (19-1, 13 KOs) fought in the undercard of Golovkin’s unification fight against David Lemieux last year at the Madison Square Garden, where he won via unanimous decision over Eamonn O’Kane.
