‘GGG’ battered Brook into submission through five hard-fought and entertaining rounds with the predominant welterweight, cementing his place as one of the top two pound for pound fighters in the world.
Brook’s trainer Dominic Ingle pulled the Briton out after he suffered a broken orbital bone and Sanchez believes it was the right decision to save ‘The Special One’ from taking any further punishment.
“I’ve said anybody from 154 to 168 wouldn’t go 12 rounds with him,” said Sanchez.
“Kell is a very good fighter as you saw but eventually they’re going to break down and eventually his power and ability to land punches are going to take effect like it did with Kell.
“I’m happy the corner protected Kell because these guys aren’t going to quit because he is a warrior and Dom felt it was necessary at that point. I’m glad everybody is fine.”
As Brook heads back down six pounds to 154, Golovkin already has two potential challengers to his middleweight crown. Danny Jacobs has already been put forward as mandatory and the only other champion at 160, Billy Joe Saunders also wants a piece of the action.
Saunders is set to fight on the Tyson Fury v Wladimir Klitschko rematch bill next month but says he’s ready to accept a fight with Golovkin on whatever date is put to him after October 29.
