#4 Seth Rollins
The Intercontinental champion is currently in a blood feud with his former brother, Dean Ambrose in what promises to be a dynamite program. Hopefully, the end of it sees Rollins catapulted into the main event scene where he absolutely belongs. It could be argued that the Kingslayer was the man who should have ended Brock Lesnar's 504-day long title reign at SummerSlam but anyway, he remains a strong choice to stand tall at the end of the Royal Rumble match. Since the Shield initially broke up in 2014, Rollins has entered only one Rumble match and that too, he had a Raw tag title match to take care of afterwards. So maybe 2019 could be Seth Rollins' defining Royal Rumble moment.
Who would Seth Rollins face: Brock Lesnar
As mouth-watering a clash between Seth Rollins and Daniel Bryan is, the story lies on the Red brand for the Kingslayer. He has shown open discontent on TV with Brock Lesnar's farcical Universal title reign, so maybe that is the direction WWE is heading in. Rollins is, in fact, Lesnar's rumoured opponent at WrestleMania as things stand. It would be some sight to see the rematch between these two champions. Only this time, Rollins is not a coward. The match could go in a similar way to the Beast's classics with CM Punk, AJ Styles and Daniel Bryan with the only difference being that the underdog babyface actually wins. Seth Rollins winning the Universal Championship from Lesnar at WrestleMania 35 would be poetic, considering it was him who took the WWE title off the beast at 'Mania 31 four years ago.
