25 Countries that the current roster can represent in the WWE World Cup 

#12 American Samoa - Anyone from The Rock's family or Samoa Joe.

The Rock and Roman Reigns

American Samoa has one of the richest histories in Professional Wrestling. Most of it is largely thanks to the Anoa'i family. The Rock's maternal grandfather Peter Maivia was the first Samoan superstar and from him several of his family

The current Samoan superstars in WWE include The Usos and Roman Reigns. But with these three there is also another Samoan superstar- Samoa Joe. Joe has had plenty of success all over the world and is currently involved in a WWE Championship feud with AJ Styles. All the Samoans have achieved great success in WWE.

The fact that Roman Reigns already has a match at Crown Jewel probably means he won't be in the World Cup. As Usos are a tag team, that leaves Samoa Joe to be the ideal participant in the tournament.
