#3 Seth Rollins
Does Seth Rollins really need to win a tournament which will probably have next-to-no significance once Crown Jewel is over? No. No, he does not.
However, with Rollins and Roman Reigns at odds with Dean Ambrose on a seemingly weekly basis at the moment, it’s inevitable that “The Kingslayer” and “The Big Dog” will soon find themselves embroiled in some heated altercations of their own.
For that reason, a Rollins victory in the World Cup could be a good way to kick-start a battle with Reigns over who is “the best in the world” out of the two men, and it would tie into the current storyline by further devaluing the importance of Ambrose to The Shield.
Besides, Rollins legitimately feels that he is "the best in the world", as he recently said before namechecking Kenny Omega as somebody he wants to face one day, so the new nickname would be a suitable fit for him.
