#3 Shawn Michaels
Shawn Michaels returned to WWE TV this past week and managed to get into a verbal confrontation with The Undertaker. With news that The Heartbreak Kid could be the special guest referee in Australia next month before making an in-ring return in Saudia Arabia, it's easy to see the direction that this feud could take.
Michaels has been one of the most popular wrestlers in the world throughout his career, but the former World Champion would definitely add the shock factor to the show if he was to turn heel on The Undertaker and set up another incredible match between two of the biggest legends in the business.
