#4 A potential dream match with Shawn Michaels

As untimely as it sounds, the only two superstars Shawn Michaels could legitimately collide with in his final outing are The Undertaker and AJ Styles.
While Michaels had feuded with The Phenom before, it is time he tests his mettle against The Phenomenal One, and give the fans something they have always wanted to see.
There's no denying that Vince McMahon acknowledged the idea of having HBK lock horns with AJ Styles in a dream match, but the plan never worked out.
Considering that The Show-Stopper has returned to the squared circle, colliding with The Phenomenal One could make things easy for him, and would possibly entice pro wrestling fans.
Something like this could excite AJ Styles into signing a longer deal.
