#2 John Cena
John Cena and Daniel Bryan are currently the top guys in WWE. Both of them are incredible in-ring performers and have great promo skills.
The WWE Universe is also immensely invested in both Bryan and Cena and these two men always get a reaction from the crowd.
Cena is currently working as a part-timer and hasn't been seen on TV for a long time. It would be shocking to see Cena enter the Royal Rumble match. He can win the match and go on to face Bryan at Wrestlemania 35.
Cena is currently tied with Ric Flair to hold the most world championships but that could change at Wrestlemania 35, he could defeat Bryan and win the WWE championship and become the first ever man to win 17 world championships.
If the feud is booked properly we can be sure that this rivalry will blow the roof off and these two men will certainly deliver a phenomenal match.
