Gennady Golovkin's future seems simple. If there is no rematch with Saul "Canelo" Alvarez - then GGG and his team might explore the possibility of heading up to 168-pounds in search of more challenges.

Golovkin (37-0, 33 KOs) is scheduled to defend his IBF, IBO, WBA, WBC middleweight titles against Canelo (49-0, 34 KOs) on September 16th at a venue and location to be determined.

"The fight with Canelo is the only thing on our minds, we are going to concentrate on that fight. If we do not do well, then it doesn't matter what we think right now. We have to prove that Golovkin is the best middleweight in the world. And if we do and the fight is good - there can be a rematch," Sanchez told ESPN Deportes.

The fight will be carried on HBO Pay-Per-View and is viewed as the biggest boxing match since Floyd Mayweather Jr. and Manny Pacquiao collided in May of 2015.

If Golovkin wins, and Canelo does not exercise his right to an immediate rematch, then GGG may head to 168.

"These fights are the ones we need. We have not had a Vazquez-Marquez, Barrera-Morales, Marquez-Pacquiao [in a long time]. If we can have a rematch, we would welcome that. But if not, I think Golovkin already did what he had to do at that weight, and we would raise the possibility of climbing up to 168 pounds," said Sanchez.

Golovkin is only missing one middleweight world title, the WBO which is held by Billy Joe Saunders, who is scheduled to make a mandatory defense in July. Sanchez believes a victory over Canelo could very well be the final piece of GGG's middleweight run. The boxer is already 35 years old and can't afford to waste time by waiting for a Saunders bout - especially when you consider that Golovkin has several mandatory obligations creeping up.
