WWE Royal Rumble 2018: Predicting All 30 Entrants
14. Rey Mysterio
Rey Mysterio is a prime candidate for a shock return to the world's biggest wrestling promotion in 2018. The company were reportedly in negotiations with the former WWE and World Heavyweight Champion last year, but ultimately passed following issues with his representation. That presumably wouldn't be as big an issue for a one-off deal like this, as they'd only have to contend with Rey and his troublesome manager, Konnan, on a single occasion.
Mysterio hasn't appeared for WWE since April 2014. His unclear Lucha Underground contractual status may complicate matters, but his appearance would draw a monstrous pop.
