WWE Royal Rumble 2017: 10 Potential Main Events
3. John Cena Vs. AJ Styles
Rumors have already been circulating regarding John Cena's involvement at the Royal Rumble. He could return as a surprise entrant in the 30-man time-dispersed battle royal, but it's also possible that the 15-time world champion could look to settle his unfinished business with the reigning WWE Champion, AJ Styles.
WWE could go several ways with this, but one way would be to save Cena/Styles III for WrestleMania with John winning the Royal Rumble to earn a title shot. After all, wouldn't Cena's attempt at a legendary, record-tying 16th world championship be worthy of WrestleMania?
While that's an option, it's probably not the route WWE will take. Instead, they could opt to move up Cena's quest for history to the equally-deserving setting of the 2017 Royal Rumble. In addition, it's also been reported that WWE wants to go with Cena vs. The Undertaker for WrestleMania 33, after Cena's injury forced them to cancel plans for that match last year. John can't very well do that if he's wrestling AJ Styles at the Showcase of the Immortals.
Including his triple threat victory this past October, AJ Styles has defeated John Cena at three major events in 2016 (Money In The Bank, SummerSlam, and No Mercy). Cena's bound to get some sort of payback sooner or later, and WWE may look for that payoff to come January 29 at the Royal Rumble.
