Abel Sanchez, the head trainer for WBA, WBC, IBO middleweight champion Gennady Golovkin (38-0-1, 34 KOs), feels very confident hat his boxer will score a knockout in the upcoming rematch with Canelo Alvarez (49-1-2, 34 KOs) - unless the Mexican superstar runs for the entire fight.

But Canelo has promised to trade punches when he faces the champion - on September 15th at the T-Mobile Arena in Las Vegas.

They first collided in September 2017, and fought to controversial twelve round split draw at the same Las Vegas venue.

They were initially set to collide on May 5th - until Canelo withdrew after testing positive for the banned substance clenbuterol.

And then a furious Golovkin accused Canelo of being a drugs cheat - which incensed the Mexican fighter.

In the first contest, Sanchez was very critical of Canelo - and claimed that he ran away from a toe to toe fight with Golovkin.

"They are both so angry, that if Canelo decides to knock out Golovkin he will have to throw punches with that intention - and that means he will be knocked out, and we will see who will take the most," said Sanchez to ESPN Deportes.

"But I feel that the only way that Canelo does not go knocked out is for him to run - and he knows it, and that's why he does not want to go face to face with Golovkin. [Golovkin] will come out attacking and he will look for the knockout. We will fight like we did in the first contest, we won the first one."

"There will be no press conference or face off. We already made a press conference on Monday and we will do the promotion [for the rematch]. We will move the fight as it should move. If Canelo does not want to do anything [to promote the fight], we can not do anything about it."
