1: John Cena
The WWE World Cup is not likely to mean anything in the long run, and having John Cena walk out of Saudi Arabia with the trophy would be a nice way of sending the live audience home happy if nothing else.
Despite his status as one of the company's top stars, Cena has not had much luck in the way of victories over the last 12 months and having him overcome three opponents would be again to remind the WWE Universe of just how highly the company values his presence.

With Cena still working on a film with Jackie Chan in China, there is every chance that the WWE won't want to have him wrestle in three long, gruelling matches, but the aforementioned double knock-out scenario with Ziggler and Rollins could provide the WWE with the perfect way around that problem.
