#4 Drew McIntyre vs. Dolph Ziggler
Another major return that occurred at the PPV was Dolph Ziggler, who entered the men's Royal Rumble match as one of the surprise entrants. He was last seen on the last Raw of 2018, where Drew McIntyre defeated the latter in a steel cage match.
Since then there were rumors of Ziggler leaving WWE to pursue his career on some other of his interests. He even confirmed his hiatus from WWE and said every one to not expect him to return at the Royal Rumble because he was booked for a comedy show in Phoenix itself.
Ziggler not only entered the Royal Rumble match but eliminated his old nemesis, McIntyre. McIntyre was heavily favoured to win this year's Rumble match, and he would definitely get revenge from Ziggler for his elimination.
This could mean that WWE continues the feud between The Showoff and The Scottish Psychopath until WrestleMania where McIntyre will finally end his feud as well as Ziggler's career by defeating him once and for all.
