#4 AJ Styles wins clean
AJ Styles recently completed a year as WWE Champion. However, he has spent most of his time as champion being part of underwhelming storylines against Jinder Mahal, Sami Zayn and Kevin Owens, a disappointing feud against Shinsuke Nakamura (given the high standard of matches they put on in NJPW) and Rusev.
His recent feuds against Samoa Joe and Daniel Bryan proved to be a saving grace to his run as champion. However, he still needs a statement victory and there can be no bigger statement than defeating Brock Lesnar clean in the middle of a WWE ring given how protected Lesnar has been throughout his run in WWE.
Though it sounds good on paper, it is a well-known fact that size does matter in WWE and Vince McMahon is unlikely to give Styles a clean victory over a much-bigger Lesnar.
The match will undoubtedly be good given the technician Styles is in the ring but probably no one expects him to win clean, unless, WWE decides to swerve us, just like they did at Survivor Series 2016.
