#2 Sting
The Undertaker has already been announced as one of the stars who will be traveling out to Saudi Arabia for the October 31st show, with rumors now suggesting that The Fiend could be the man who steps up to the challenge of The Deadman.
It's hard to imagine that after WWE put Undertaker up against Goldberg on the last show in The Middle East, there aren't people in the company pushing for the biggest fantasy match in wrestling history. Sting has been holding out for a match against The Undertaker for a number of years and he's still considered to be available if the company makes the call.
Goldberg's return match didn't go to plan, which means that a match between The Deadman and The Icon could only be a step up from the main event of the show back in June. It would allow the WWE Universe to finally witness the match they have longed to see since the days of WCW, and it would mean that Sting can then retire post a long awaited match.
