#4 Ending his career with a solid retirement speech interrupted by Sting
Being two of the most legendary superstars to ever step foot between the ropes, it's a damn shame that the Undertaker and Sting have never competed against each other, in any capacity.
While there was a time when there were rumors of a match being booked for WrestleMania 32, the company scrapped it eventually and changed their plans.

Sting's unfortunate injury ruled out the possibility of ever crossing paths with the Phenom, but he still remains intact on his willingness to share a WrestleMania moment with the Undertaker.
After having completed almost three decades in this business, it would be ideal for the Deadman to retire with a solid speech thanking the fans for their support throughout, and if booked correctly, the segment could take the world by storm with the interruption of Sting.
Both the competitors deserve to end their careers on a high note, and since the crowd have always been yearning for a confrontation, shaking hands and embracing each other's humble end would be a treat to the eyes.
