5. Trish Stratus' return at The Royal Rumble PPV in the women's Rumble match (2.3 million views) Mysterio and Styles have actually squared off once before. They wrestled in the U.K. for a 5 Star Wrestling event in January of 2016. Styles defeated Mysterio via pinfall when Mysterio tried to hit him with a seated senton from the top rope. Styles caught Mysterio and reversed it into the Styles Clash for the win. As noted, Mysterio is currently a free agent although PWInsider reported that WWE officials took note of the reaction that he received, and that it may lead to more appearances for the company. They have had talks in the past, however WWE wants him back full time while Mysterio will only work a limited schedule.
