10 Ex-WWE Superstars With Unfinished Business

10. Alberto Del Rio

What Happened: After an amazing early push that saw him win the Royal Rumble, bag a Money In The Bank contract and win his first World Title courtesy of a cash-in on a white-hot CM Punk (yeah, it didn't really benefit anyone in hindsight, did it?), Del Rio fell in and out of the main event scene before falling out with the company after an altercation with a WWE employee. Del Rio was released like a poo after a hot curry, and headed to Lucha Underground by way of AAA.

How To Book A Return: A simple Rumble return would do the job for someone like Del Rio - give him the chance to come out, hit all his badass spots (god damn we love that enziguri) and flirt with some potential future feuds. Oh, and obviously, it has to be with a full Ricardo Rodriguez intro. Splitting those dudes up was criminal.
