Prolific knockout artist Saul Canelo Alvarez and granite-chinned Gennady Golovkin will complete their epic trilogy of fights on Saturday night.
GGG is set to move up to super-middleweight to challenge his bitter rival for his undisputed WBA, WBC, IBF and WBO world titles on September 17.
Back in 2017, Golovkin and Canelo shared the ring for the first time in an extremely entertaining and competitive 12-round fight that ended in a disputed draw which many felt robbed the Kazakhstani fighter of a victory.
The following year, Alvarez won a narrow majority decision in their rematch but GGG has always insisted that he won both fights and now he’ll get his chance at revenge.
However, in order to get his long-awaited win over the Mexican superstar, Golovkin must once again be able to stand up to his power which is now legendary.
Álvarez turned professional at 15 and knocked out 11 of his first 13 opponents, who were all significantly older than him.
Now, Canelo, 32, is one of the most feared punchers in boxing after brutally knocking out the likes of Liam Smith, Amir Khan, James Kirkland, and Sergey Kovalev.
Even when he doesn’t completely put you out, he is able to cause significant damage.

Just ask Billy Joe Saunders who suffered a fractured orbital when he fought Canelo or Callum Smith whose arms were swollen after blocking the super-middleweight king’s shots for 12 rounds.
During his 61-fight career which has included 39 stoppage wins, it seems like only one man has been able to take his power without any trouble and that’s Golovkin.
The 40-year-old has eaten countless power punches from Canelo during their rivalry and has never hit the floor or looked slightly bothered about what was coming his way.
Famously, in round nine of their first fight, Canelo caught GGG with a perfect punch, but his opponent remained unmoved, and the Mexican even appeared to look slightly worried about the apparent zombie standing in front of him.
“I remember that punch,” Golovkin told DAZN. “I let it get through. It wasn’t, I don’t what to call it – it wasn’t hard.
“It felt kind of like a slap, I guess. Or a sliding punch but it didn’t hurt too much.”
Golovkin has arguably the most durable chin in boxing history, having never been knocked down or otherwise stopped in a total of 394 fights, 44 as a professional and 350 as an amateur.
However, some believe that his incredible record will come to an end this weekend at the T-Mobile Arena in Las Vegas, mainly because of his advancing age.
It’s rare to see someone still at the top of their game at 40 and former Canelo opponent Saunders believes Golovkin will no longer be able to stand up to power shots like he used to.
He told talkSPORT: “Obviously, the two fights previously were two good fights but I just think the age factor now has just crept in a little bit more than it did a few years ago.
“It’s very clever from Canelo’s team, coming off a loss and then looking very good against Golovkin. I think the age factor is gonna lead to the old man legs coming into [play] and maybe even a stoppage.
“Age is a big factor in this fight now. The man is 40 years of age, and you can’t really expect him to roll back the clock to five or 10 years ago when he was at his best.
“I’ve got to go with a Canelo win. Maybe from rounds 8-12 stoppage.”
After nearly 400 fights of seemingly being bulletproof, we certainly won’t be backing against GGG’s chin in this one, even if he is going up against one of the biggest pound-for-pound punchers in boxing history.
