It's been said before, but 2016 will definitely be WWE's last chance to book one of the most sought-after matches in wrestling history. Stretching back as far as the 1990's, people have wanted to see Sting tangle with The Undertaker. For many, the match represents the true battle between WCW and WWE. It's genuinely hard to argue with that point. The Undertaker is coming towards the end of his active in-ring career, that much is certain. For the past few years, the legendary figure has noticeably aged with each passing performance, despite the storyline claims that he's immortal. For Sting, years on the road have started to catch up with him. No 'spring chicken', there are worries his recent injuries will prevent him from wrestling again. Even so, people hope that Sting vs. 'Taker can take place. The only fitting place to make it happen would be WrestleMania. There's a good chance that fans wouldn't even be disappointed if the bout only went 10-15 minutes in length, because the idea of seeing these icons square off is what WrestleMania means to a lot of folks. 'Mania 32 is arguably the last opportunity.
