According to The Wrestling Observer Newsletter, Vince McMahon already has decided The Undertaker’s WrestleMania 32 opponent in his head - It will either be Sting or Brock Lesnar.

If Sting vs. Undertaker does happen, SummerSlam and WrestleMania 32 are the most likely events the match will take place.

Both Sting and Undertaker are rumoured for Sunday's Battleground. It will be interesting to see if their paths cross, if they do it will be almost a certain indication that they will be wrestling at WrestleMania 32.
