#5 AJ Styles vs Shinsuke Nakamura vs Finn Balor
Finn Balor deserves to be in the World Title picture, simple. The man is a proven headliner, has the talent, the charisma and, no matter what the WWE management thinks, he is definitely over with the fans. So, if he simply can't challenge for the Universal Title (thank you, Roman and Brock), why not have him move to Smackdown to challenge for the WWE Title. Even better, why not add him to the already speculated match between Styles and Nakamura? Make it a Triple Threat Match and given ample amount of time, watch these three produce the magic that we need at Wrestlemania.
When Styles was called up to face Balor at TLC, speculations rose that WWE was planning a long term storyline involving the two former Bullet Club leaders. Balor has mostly been directionless since his return and has even been robbed of his rematch against The Beast at Royal Rumble. Styles and Nakamura are most certainly on course to the mega clash at Wrestlemania, but WWE could add a nice twist to it by having Balor win the Rumble. He could then go over to Smackdown to challenge Styles for his Title and then Nakamura could be added to this feud after Fastlane in February to produce what could possibly turn out to be the best WWE Title match in Wrestlemania History.
Imagine the reaction of Wrestling Community, watching 3 NJPW alumni, fighting at WWE's premier event for the most prestigious title in WWE. Now that's "TOO SWEET".
