#1 AJ Styles
AJ Styles could be a dream opponent for Seth Rollins, and they have the potential to produce one of the best feuds in recent memory. Though Styles is currently part of Smackdown Live, there is a possibility to switch brands in the Superstar Shake-up.
Considering Styles has faced most of the superstars of the blue brand, we might see the Phenomenal One on the RAW this year. Moreover, Styles has been part of the blue brand since the inception of the brand split.
Styles will fight Randy Orton at Showcase of Immortals where the two men will compete to prove their supremacy. The Phenomenal One held the WWE Title twice on Smackdown Live, and his last run was the eighth longest World Title reign in recent history. Without a shadow of a doubt, he could be a deserving candidate to be the Universal Title challenger.
There is no denying that Styles and Rollins are spectacular performers in the squared circle. Besides the dexterity in the ring, they also have impressive mic skills. It could be a dream feud to headline Summerslam this year.
