5 ways WWE could intensify John Cena vs The Undertaker

#2 A WWE Legend could turn up as the Special Guest Referee

A possible mainstream inclusion could be monumental

Well, there's no denying that the in-ring quality for John Cena vs The Undertaker has become a debatable issue but despite the conflict, a possible mainstream inclusion could make this feud more interesting.

The last time an Undertaker match had a Special Guest Referee was when Shawn Michaels donned the white stripes' in a historical bout against Triple H at WrestleMania 28. The match told a solid story and Michael's inclusion brought some high-profile popcorn entertainment.

Therefore, if the company is looking to elevate the standards of this match, an inclusion from an established legend could bring the house down in New Orleans.

John Cena vs The Undertaker could perhaps be the greatest match in WrestleMania history and superstars like Stone Cold or Shawn Michaels could act as mainstream additions.
