Fans are still upset with WWE over the fact that top AEW star and The Undertaker didn't square up in the ring. Wrestling World had a debate over which two wrestlers that never faced each other would have an iconic clash. A plethora of fans still hold a grudge for not being able to witness Sting versus The Undertaker.For several years, the wrestling world wanted to see both WWE Hall of Famers wrestle each other. Unfortunately, that never happened. One of the main reasons the match never became a reality was that the two icons were never in the same promotion. The Undertaker was in WWE for his entire career while Sting was moving around between promotions.In 2014, Sting made his WWE debut and people started talking again about the Undertaker and former WCW World Champion battling each other. But once again, it never happened. Sting was sidelined due to a back injury after his match against Seth Rollins.Thus, when a fan asked a question on Twitter about which dream match people would have loved to watch, there was a plethora of fans who named the current AEW star vs The Undertaker as the match they wanted to see.Real-EST 🚀@WWEREALESTWhich dream match would you have loved to see the most?1621116Which dream match would you have loved to see the most? https://t.co/j75SDYT81CLJ@lightingjayrva@WWEREALEST Definitely Sting vs. The Undertaker it really needed to happen to be honest.30@WWEREALEST Definitely Sting vs. The Undertaker it really needed to happen to be honest.Jevonte 💫@Jtaexix@WWEREALEST Definitely Sting and undertaker, wrestlemania 27 would have been the time to do it18@WWEREALEST Definitely Sting and undertaker, wrestlemania 27 would have been the time to do itSkyler Steele@TheRealSkySteel@WWEREALEST Undertaker vs Sting would’ve been the biggest draw I think, AJ vs Michaels would be the best in ring match, Brock vs Batista would be cool for a main event of Smackdown or Raw, & I’m not sure who’s asking for Rock vs Orton.
