#2: The Phenomenal One, no more?

Much like his Bullet Club brothers, AJ Styles' contract is also up for renewal according to the PWInsider, though according to them, it will expire in April next year.
Styles, who joined the company at the 2016 Royal Rumble has been one of the company's most successful stars, winning the WWE Championship twice, as well as the United States Championship.
After a year-long reign as SmackDown Live's top stars, Styles recently lost the WWE Championship to Daniel Bryan, though will face him at TLC this Sunday in his rematch.
Win or lose, Styles is still one of SmackDown's most beloved Superstars, though apparently contract negotiations between him and the company have been slow, as they've struggled to reach a deal.
It would be a real shame for the WWE to lose the Phenomenal One in 2019.
