The duo will square off at the T-Mobile Arena for the WBA (Super), WBC, IBF, and IBO middleweight titles in one of the most eagerly anticipated bouts for years.
Golovkin is the defending champion and favourite and will take an unbeaten record into the fight having vanquished all 37 of his opponents over a nine-year career.
Alvarez has a draw and just one blip on his CV but that did come against Floyd Mayweather four years ago and he has taken care of the likes of James Kirkland and Amir Khan since.
His last outing was something of a non-event, however, as Julio César Chávez Jr opted against throwing any punches of note and succumbed to a unanimous points decision in Las Vegas.
The crowd were not happy with the 12 rounds of one-way traffic but were appeased afterwards as the winner announced the mega-fight with Golovkin.
Triple G was there ringside to add to the spectacle and the fighters will now have to deliver and live up to the hype, which is sure to reach fever pitch as fight night approaches.
The man who is a hero in Kazakhstan is nine years older than his opponent and whether that plays any part in proceedings only time will tell, but Alvarez has fought 51 professional fights to Golovkin’s 37.
With so much at stake, preparation will be key and, despite there still being three months to the scrap, Alvarez has been seen working hard in the gym and sparring to get himself in tip-top condition.
There have been accusations in recent years that he has avoided a showdown with GGG but, after stating “I fear no man”, he will now put his reputation on the line against the power of the Kazakh Thunder.
Despite his glittering career, Golovkin said that fighting Alvarez is “the big fight I have been seeking all my life and a chance to prove I am the greatest”. For those who fancy a flutter on Golovkin, the boxing betting boffins at Free Super Tips will give punters all the information and statistics required closer to the fight.
There have been many fights that have not lived up to their billing but, with two warriors going toe-to-toe, the packed house of 20,000 fans will surely get their money’s worth this time around.
Their differing styles mean that it has all the makings of a classic as Golovkin knows only one way to move – forward.
He will stalk Alvarez around the ring and, like a matador, pick him off with strength-sapping jabs before unleashing his trademark power blows as he seeks a 34th knockout.
Alvarez will welcome the God of War’s advances as he is a masterful counterpuncher and will hope his opponent provides him with a target.
It is not overstating the fact that this is a huge fight and the pair lit the touch paper with a verbal exchange after the Chavez fight as Golovkin wished Alvarez “good luck” for September.
“Luck is for the mediocre people,” ‘Canelo’ responded, and there is clearly nothing mediocre about these two.
