It's one of the few dream matches that seems to actually be attainable in professional wrestling. Shawn Michaels is retired, so he can never face off against The Rock or Daniel Bryan, and the same goes for Stone Cold Steve Austin, whose dream bouts with the likes of CM Punk or Goldberg are just a fantasy nowadays. But with The Undertaker still employed by WWE and Sting rapidly edging closer to a in-ring debut for Vince McMahon's company, it's with much excitement that many fans are predicting a bout between the two in the not-too-distant future. The two men may differ in terms of their wrestling style, and their careers have never crossed paths due to opposing wrestling promotions, but a Sting vs Undertaker match has all the intrigue, psychology, and potential an out and out classic. Sure, their combined age of 104 means that a high-profile bout between the pair might be slow, lethargic, and could in fact be a royal stinker, but we're willing to give this dream match the benefit of the doubt; both men were, at their prime, two of the best wrestlers in the business, both men have routinely delivered incredible promo work throughout their lengthy career, and both men have millions of loyal fans worldwide. A showcase between The Icon and The Phenom would be an encounter for the ages, and a surefire pay-per-view sellout, too. Here are 10 steps towards booking a clash between the two legends.
