Abel Sanchez, the trainer of middleweight Gennady Golovkin, rejects the claims that his boxer faded in the second half of the rematch with Saul "Canelo" Alvarez.

On September 15, in very competitive fight, Canelo won a twelve round majority decision over Golovkin to capture the WBC, WBA middleweight titles.

Golovkin (38-1-1, 34 KOs) suffered his first career defeat, based on scores of 114-114, 115-113 and 115-113.

In the later rounds, Golovkin was noticeably breathing in a heavy manner in the corner and during the in-ring action as Canelo was pressing forward and throwing a lot of punches.

Many observers felt Golovkin was tiring out from the constant pressure of Canelo.

"No, I disagree with that. Gennady is.. some European amateur systems encourage that deep breathing, and when he was coming up as an amateur that was encouraged in the corner, a lot of them do that, breathe deep in to fill their lungs. If he had been fatigued, he wouldn't have been able to do what he did in the 11th and 12th," Sanchez stated during chat session on Reddit.

Sanchez continued to rain down praise on Canelo - for the Mexican star's performance and his ability to withstand the hard punches of Golovkin.

"I think Canelo fought a great fight, Golovkin fought a great fight, we were in the midst of a classic like Hagler-Leonard. We can say that Hagler didn't look like himself that fight, but he looked great," Sanchez said.

"We're at the elite level, where there's guys like Gennady that can take a shot. There's guys that today and in the past that can take a shot at the elite level and give us thrilling fights. Canelo's one of them, he took some very very good shots. He wobbled a little in the 11th or 10th, but he stood up so he's obviously one of those elite guys."
