Last week, 90,000 fans packed Wembley Stadium in London for a heavyweight thriller.
Saturday night's post-fight announcement - with "Triple G" striding from ringside to join in - was the most electrifying moment at the T-Mobile Arena in Las Vegas, where Alvarez dominated Chavez Jr. for 12 rounds in a non-title bout fought at a catchweight of 164 pounds.
Canelo is undefeated since his 2013 loss to Floyd Mayweather and has taken the scalps of Miguel Cotto, James Kirkland, Erislandy Lara, Shane Mosley and Khan over the past five years.
It turns out that both sides already discussed plans for the mega fight, with the Alvarez camp confident of defeating Chavez. It was later revealed that Pacquiao, who struggled to land punches, was fighting with an undisclosed shoulder injury.
"And that's what you see, the build-up from that fight to now, he's gotten better and better and you can't see that with all generations of fighters".
News of this proposed fight comes one week after Anthony Joshua and Wladimir Klitschko carried out an 11 round thriller in Wembley Arena, to inject some life back into the boxing scene.
The Cinco de Mayo weekend has been popular for major fights for some time.
The reigning lineal middleweight champion Alvarez (49-1-1, 34 knockouts) was too quick for the slow of foot and slow of hand Chavez Jr (50-3-1, 32 knockouts), closing the taller Chavez's left eye with his unstoppable right hand.
"Tonight, I showed I could move, I could box, I showed as a fighter I can do all things", Canelo said after the bout. "It can be a big boost to my career if I can win this fight".
Following Alvarez's complete domination over Mexican rival Julio Cesar Chavez Jr., the bout was made OFFICIAL. Chavez is 6-foot-1 and has a 73-inch reach. Right now, I think everyone is excited for September. "I'm just looking forward to giving the public a great fight". He's guaranteed $5 million.
"I thought he was going to fight". "I've been training with sparring partners who are much bigger than me".
There have been plenty of barbs traded since the fight was announced.
Chavez will have had to cut weight, then gain weight, while Alvarez has stayed steady throughout.
After the battle Alvarez-Chavez came out to the ring king of the Middleweight Gennady Golovkin to officially confirm the fight with Soulem. At stake will be Golovkin's WBC, IBF, WBA, and (less importantly) IBO Middleweight belts in this highly coveted matchup between two of the best boxers in the world. The 31-year-old is working under renowned trainer Ignacio "Nacho" Beristain for the first time and is insisting he's prepared and motivated. I saw him running and getting in shape.
In a showcase of pure excellence in boxing, Canelo defeated Julio Cesar Chavez Jr. via unanimous decision (120-108, 120-108, 120-108). Saturday's night HBO pay-per-view showdown may not be for a title, but plenty is at stake. They had the opportunity to make this fight years ago.
