Canelo Alvarez has been a world champion across four divisions for more than a decade and naturally, is used to being called out. However, he didn't think someone he publicly praised in Terence Crawford would join that club.

Yet, after realizing that he was serious, the two came to an agreement and will officially square off on September 13 at Allegiant Stadium in Las Vegas.

Since it was announced, Crawford (41-0, 31 KOs) has walked around like a man who knows he can’t and won’t lose. If he wins, the former four-division champ believes he should be cemented as a top-five fighter of all time. WBC interim junior middleweight champion Vergil Ortiz Jr however, will place him even higher on a personal level if he gets the job done.

“I don’t think he does, but if he beats Canelo, he’ll be my number one fighter of all-time,” Ortiz told Ring Champs with Ak & Barak on their YouTube channel.

Alvarez (63-2-2, 39 KOs) hasn’t shown an ounce of fear when facing off with Crawford during the lead-up. He respects his accomplishments, but considering their size difference, isn’t too worried about what he brings to the table. As of late, Alvarez hasn’t worried about anyone really.

In his last six fights, the undisputed super middleweight champ has cruised to the finish line, including against William Scull May 3, at The Venue in Riyadh, Saudi Arabia. Crawford, similarly, hasn’t had too much trouble during his last handful of ring appearances either.

After dismantling and walking through Errol Spence Jr. to become an undisputed welterweight champion, Crawford crashed the junior middleweight party last year, winning the WBA title against then-unbeaten titleholder Israil Madrimov.

Although technically he's a junior middleweight champion, Ortiz doesn't view him as one. Now, of course, skills pay the bills. They always have. But when you’re giving up that much in weight, Ortiz doesn’t know how Crawford could overcome that disadvantage.

"I respect Crawford and everything he’s doing, but he just moved up from 147, so I’m going to treat him like a 147-pounder. He’s jumping up three weight classes to fight someone who was the number one fighter in all of boxing. The jump would be hard even if it was some top 10 guy. Canelo, he has the size and strength advantage.

"I do think Crawford edges him out in IQ. I just think the weight difference is gonna be the deciding factor here, Crawford bit off a little more than he can chew. I’m not saying he can’t, I’m just picking Canelo to win but if he does, he’ll be my number one fighter of all time."
