Former WBC junior middleweight champion Jermell Charlo is giving Terence Crawford absolutely no chance of beating of beating welterweight rival Errol Spence.

Charlo and Spence share the same trainer in Derrick James.

Crawford vs. Spence is the biggest fight to be made in the welterweight division and certainly one of the biggest fights to be made in boxing.

Crawford and Spence were both in action in recent months, and they are not heading in the direction of facing each other this year.

"I definitely believe that Terence Crawford stands zero chance against Errol Spence. Zero. Zero. Errol is the bigger, monster fighter," Charlo told TMZ Sports.

Last month, Crawford stopped Amir Khan in six rounds at Madison Square Garden in New York City. And Spence dominated four division champion Mikey Garcia in March at AT&T Stadium in Texas.

Crawford's next fight is unknown, although Amir Khan is an option.

Spence is going to collide with WBC welterweight champion Shawn Porter in a high stakes unification in the coming months, with the Barclays Center in Brooklyn being a targeted location for the bout.

Due to their network affiliations, a unification will be tough to make. Crawford is contractually tied to Top Rank, who have an exclusive content deal with ESPN. And Spence is under the Premier Boxing Champions banner, who have content deals with Fox Sports and Showtime.
