#4: Sami Zayn

The Underdog from Underground is one of the latest additions to the "dark" side of Smackdown Live, with a shocking heel turn during the Hell in a Cell main-event. He reignited his friendship with Kevin Owens and has become an entertaining sight to watch.
Sami Zayn is one of the finest in-ring talents in WWE, arguably only behind AJ Styles and Seth Rollins. He has produced spectacular wrestling performances from time-to-time and a push to the main-event scene will be well deserved for the former NXT champion. His in-ring psychology is second to none and this has resulted in him connecting with the audiences extremely well.

Zayn winning the Championship as a heel would not be a great decision but a Styles-Sami match can tear the house down if given proper time at Royal Rumble.
