#2 AJ Styles
AJ Styles and Shawn Michaels were speculated to collide. However, the rumor never became reality (see video below). Styles and Michaels working a match would be epic. With recent events surrounding Michaels' return, could this happen? Perhaps following WWE Super Show-Down, more answers could follow.
In the ring, Styles and Michaels are similar. They have aerial ability, they implement aggressive strikes, and they even utilise submissions. With these tw fans can expect a WrestleMania standard classic.
WWE would immensely benefit from their pairing. Moreover, what makes this pairing more special is both wrestlers have led extremely popular factions. Styles led Bullet Club, whereas Michaels led D-Generation X.
