Alvarez is scheduled to fight Gennady Golovkin in a title bout Saturday in Las Vegas. Alvarez tested positive for clenbuterol and blamed it on contaminated meat from his native Mexico.
His record of 49-1-2 with 34 knockouts includes victories over Shane Mosley, Austin Trout, Erislandry Lara, Miguel Cotto and Amir Khan, all world champions.
Because of the controversy surrounding the drug tests and the scorecards from the first fight, which most believe Golovkin (38-0-1, 34 KOs) had won, the second fight has become a grudge match thanks to GGG's outspoken comments regarding his anger.
For the most part, the animosity between the two men has had a ring of authenticity about it.
"I remember the first fight was not ideal for me or him".
"Those are the excuses that they are making because of what is coming on Saturday, which is a loss for them".
"I am bothered by all the stupid things (Golovkin's team) have been saying and I have been using it as motivation for this fight".
"Maybe they said it to get me mad, and you know what, they did it".
Golovkin is a -145 favorite, with the price on Alvarez down to +125 at some sportsbooks. But the fighters declined to hold a joint news conference when the new deal was finished, and they declined to go on a media tour or stand face to face at the final prefight news conference Wednesday. Alvarez's official purse is $5 million, and Golovkin's is $4 million. Prior to the fight it was questioned whether Golovkin could get fair treatment in Las Vegas and the scorecards seemed to prove that, with one judge, Adalaide Byrd...
This time around, Golovkin plans to leave nothing to chance, promising to take the decision out of the judge's hands by winning inside the distance.
Asked whether Canelo should be allowed to fight at all, Golovkin replied: "I'm a fighter, not a commissioner".
Sanchez has rarely wasted an opportunity to goad Alvarez's camp during the build-up, effectively daring the Mexican to adopt a more aggressive approach.
"He's promised the fans he's going to knock him out but in order to do that you have to be in range and then it gets risky", Sanchez said. "But I'm going in there to knock him out". "I've got to make sure when he's vulnerable I take advantage of that". "I think so, yes, I'll bring my belt back home".
In August, William Hill's Nevada sportsbook took a pair of $50,000 bets on Alvarez, contributing to lopsided overall action on the underdog heading into fight weekend.
