** Note this is a RUMOUR and only to be used as speculation!!!!
Apparently Vince Mcmahon has shot down the idea of Undertaker vs. Sting at WrestleMania 32. A lot of people have fantasy booked this match-up since WrestleMania 31. The idea was that Sting and Taker would both wrestle in a double retirement match where they both can end their careers. It made a bit of sense, considering both men live in Texas (site of WM32) and both were known as the anchors as their respective companies (Taker=WWE. Sting = WCW).
A lot of people were against this match-up, simply because both men are too old. And I think it would make sense for both legends to give the rub (put over) a younger talent, since they are such legends in their own senses. Also Triple H vs. Sting already kind of played on the WCW vs, WWE rivalry anyways.
Who would you like to see Undertaker or Sting to feud with if they come back for WrestleMania 32???
