Fellow boxers and critics alike have expressed varying opinions on the coming Canelo Alvarez vs. Amir Khan fight for May, where mostly see it as a lopsided one.

On paper, Khan seems formidable. He has proven his worth in the lightweight and light welterweight division but is questionable when competing as a middleweight.

Julio Cesar Chavez Jr. calls it a disgrace on his part, criticizing Alvarez for the move. He terms it an embarrassment to the middleweight division.

“A 140 [pounder] fighting at that weight [of 155]. It dishonours boxing. We all know who wins. That [fight] should not be allowed. The next fight for Chavez Jr. will be against Chris Algieri [the boxer joked]," says Chavez via Boxingscene.com.

The fight is set for a 155 lbs. catchweight, a familiar number that Alvarez has preferred to fight on. While the Mexican is likely to have no problem making that, Khan needs to bulk up and make that big step.

With that said, Alvarez will have a considerable advantage over Khan. And that doesn’t even include a celebrated technique where Alvarez could rehydrate before the fight which adds more benefit on his end.

For Khan, the move could be catastrophic. Aside from bulking up, there is the issue of him acclimatizing himself on the said weight. Could the added weight give more power to his lack of power punching? How about his chin?

Those were two of the things that many were questioning even when Khan was awaiting his chances against Manny Pacquiao. These were brought out in the open by the Filipino boxer’s camp and will be among the considerations for the upcoming fight set for May 7 at the T-Mobile Arena in Las Vegas.

Now, aside from the physical issues, there is the concern on conditioning. Khan last took the ring in May when he hardly made an impression against Chris Algieri.

With the odds stacked against him, getting over Alvarez could reap big returns for the Briton. It can "change his legacy" as singled out by Rob Lancaster of the Bleacher Report or leave him badly battered.

Khan is apparently aware of what he has gotten himself into and, unsurprisingly, stands by it as he normally does.

"I'm going to the lion's den," said Khan via BBC. "If I beat him, it will be one of the biggest upsets in boxing."

For Khan, to weather the brawl that Alvarez is expected to bring, his agility and speed will be put to the test.

If Khan wants some inspiration and tips, he could look into the upcoming fight between Conor McGregor and UFC lightweight champion Rafael dos Anjos, as previously posted. Just like him, McGregor will try to move up to a bigger weight class where will also try to defy the odds against a heavier opponent.

"I don't think I can out-power Canelo. The only way I can beat him is my speed, skill and my techniques. I think it's a 50-50 fight," he adds.
