When it could happen - WrestleMania 32 Why we can't wait - Two of the biggest names in WWE history who have never clashed on the big stage The odds are now stacked against it, but John Cena vs The Undertaker remains the very biggest match WWE could stage. Even with the story of the streak gone, this would still be WWE's old school leader against the new school leader, a main event match which we have never seen before (with the exception of some minor bouts many years ago). As long as Undertaker is officially still available it will be on WWE's mind to do the contest. They know that this could be presented as a 'Hogan vs Andre' type 'biggest match ever' in WWE history. They'll do hot business off it. As for The Undertaker, he has talked in the past about wanting to retire in his home state of Texas, so what better than a match with John Cena at WrestleMania 32 in Cowboys stadium? It's a long way off, but maybe that could be a good thing, a chance for The Deadman to get himself physically prepared. Cena would love the idea, it would undoubtedly be the biggest honour of his career, a top level Undertaker feud being the one missing piece from his achievement list. Who knows, maybe WWE even write the long awaited Cena heel turn into the feud. What a story that would be, the franchise star beating Undertaker in his last ever match in the state of Texas. Alternatively maybe it would be the chance for Undertaker to ride off into the sunset as victor, his match with Brock Lesnar was certainly a note he doesn't deserve to go out on.
