#1 Sting vs The Undertaker
One Superstar who has already been confirmed for this year's show in Saudi Arabia is The Undertaker. The Deadman opted to make the trip to The Middle East since the money for being part of the show is much more than WrestleMania, but right now his match is yet to be made official.
One man who has been looking to face The Undertaker for a long time is Sting, who has stated that he will never fully retire until he's given that match. The Undertaker's match at Crown Jewel last year proved that his best days are definitely behind him, but the Saudi Arabian fans ate it up because he's a legend.
If WWE were hoping to ever put Sting and The Undertaker in the same ring against a fanbase that wouldn't boo them out of the building then it's obvious that Saudi Arabia is the only place where that would happen.
