Abel Sanchez, trainer for IBO, WBC, WBA middleweight champion Gennady Golovkin (38-0-1, 34 KOs), wants Canelo Alvarez (49-1-2, 34 KOs) to live up to his words - by coming to fight in the upcoming rematch.

The rematch takes place on September 15th, at the T-Mobile Arena in Las Vegas.

According to Sanchez, Golovkin was very frustrated with the way the first contest played out.

Golovkin felt Canelo was not really trying to fight and was more interested in staying away for the twelve round distance.

Canelo has been promising a very aggressive approach, because he wants to knock Golovkin out - and Sanchez is hoping that he lives up to his words.

"About around the fifth or sixth round, he didn't feel like Canelo was making a fight of it. Do you remember when he fought Willie Monroe? He kept telling him 'come on, come on, let's give a fight for the fans.' He just felt like Canelo wasn't going to give the fans the fight that he had promised them," Sanchez said.

"He wanted a fight. If Canelo is going to beat him, he's going to beat him. But at least try to beat him, that's just the kind of sportsman that he is. He just wants to give his utmost inside and if he feels the other guy is not being supportive in that way, that he's not trying also, then its difficult for him.

"Golovkin is going to be aggressive regardless. He's been aggressive in every one of his fights. It all depends on Canelo. If Canelo is truthful in what he's saying, if he's a man of honor and character and comes to fight and comes to win. Im not saying to fight toe to toe, I'm just saying to come to try to knock Golovkin out like you say you're going to."
