Ahead of the September rematch, Gennady Golovkin's trainer Abel Sanchez could not resist taking more shots at Canelo Alvarez for the way he fought during their first encounter last year.

In the build-up to their middleweight title showdown that night, both fighters promised to end the fight with decisive knockouts. While the fight lived up to be a competitive boxing classic, it was Golovkin, however, who really embodied the "Mexican style" that night while many criticized Alvarez for "running" during the contest.

And despite "GGG" having the edge in the 12-round encounter for many in the boxing world, the fight was controversially scored a split-decision draw.

Sanchez was not pleased with Alvarez's tactics on the night or the scorecards of the judges. He would go on to verbally spar with the Mexican multiple times since and it only further increased when the initially scheduled May rematch fell through following Alvarez's failed drug tests for clenbuterol and consequential six-month suspension.

After plenty of negotiations, the rematch is finally set for Sept. 15, but, this time, it's personal.

Golovkin, who pushed the Nevada State Athletic Commission to punish Alvarez, would claim the 27-year-old was also a long-time user of performance enhancing drugs.

Alvarez on the other hand, who has never failed a test before, claimed the banned substance was in his system because he consumed contaminated meat in Mexico.

The Guadalajara native has since lost his respect for Golovkin and promised to knock him out this time to eliminate all doubts. But Sanchez, speaking during a satellite press conference on Tuesday, is not convinced.

"First of all, all of those same things were said prior to the first fight and it ended up being a track meet," Sanchez said, as quoted on Boxing Scene. "I think that on the 15th, when Oscar [De La Hoya] and Canelo are having breakfast, Oscar needs to remind him to make sure he brings his courage to the venue that night. He’s gonna need it. If he intends to knock out Golovkin, he’s gonna have to fight him. And if he fights him, he's gonna get knocked out. I said that before."

"He would’ve gotten knocked out the first time, but he decided to make it a track meet that night. But if he comes to fight and if he comes to knock out Golovkin, as he has said he is going to — if he doesn’t defraud the fans again, then he’s gonna get knocked out. I’ve said it and I’ll say it again."

In what was a relatively silent and ice cold press conference from both Alvarez and Golovkin, the former replied to Sanchez's remarks by defending his strategy on the night which helped him become the first fighter to avoid defeat against the unbeaten Kazakh.

"I did what I set out to do," Alvarez said through his translator. "I did what I trained to do. I did a great fight. But on September 15th, I’m gonna do the necessary adjustments and the necessary things to win."

"[Sanchez] just likes to talk. He likes to talk a lot and bring up every excuse possible. But you’ll see on September 15th what Canelo Alvarez is all about and what he’s capable of doing."

The rematch takes place at the T-Mobile Arena in Las Vegas on Sept. 15 and is expected to be one of the more lucrative fights of the year.
