Back in 2016, Amir Khan jumped up by two weight divisions to face Saul 'Canelo' Alvarez at a catch-weight for the WBC middleweight title.
Khan held his own with his boxing ability, before getting brutally knocked out cold in the sixth round.
This Saturday night at AT&T Stadium in Arlington, Texas - Khan's countryman, Billy Joe Saunders, will collide with Canelo in a WBO, WBA, WBC super middleweight unification.
Khan was up against a packed house of Mexican fans at the T-Mobile Arena in Las Vegas.
Saunders will have to contender with a hostile crowd reported to be topping 70,000.
"I’ve never fought in any atmosphere as overwhelming as that," Khan told Daily Mail. "There was a big crowd of Brits shouting for me but they couldn’t be heard. The Mexican sound was huge but with Canelo, there is something different about the noise. Something more powerful. Somehow it generates huge, unique energy on which he draws. Billy Joe had better be ready for it."
While Saunders is viewed as the quick boxer, Khan cautions that Canelo is very fast in his own right.
Khan also respects Canelo's chin and says the Mexican star has no problem with taking a good shot in order to land a better one in return.
"Beware. Everyone who watches Canelo from outside the ring thinks he’s slow. He’s not. He’s very quick through his timing. He makes you think you are in a slow-paced fight. Believe that and you make a big mistake. You will find yourself getting hit with big shots. Body and head," Khan said.
"Being quick myself, I found it fairly easy to catch him with some good shots. But he is very good at closing down the ring and has a good chin. He is happy to take punches so that he can land really telling shots. By the time he fought me his punching was becoming really powerful. He’s gone on to prove it by winning world titles up to light heavyweight and now back down a notch at super middleweight. Billy Joe has the style that can give Canelo a few problems for a few rounds. But, sorry to say, he gets knocked out in the sixth."
