#4. WWE Superstar Finn Balor
John Cena returned to WWE earlier this year to challenge Roman Reigns for the Universal Championship. Nonetheless, The Tribal Chief refused Cena's challenge and accepted Finn Balor's instead.
While Balor was about to sign the contract on SmackDown, Baron Corbin attacked him. Cena then rushed to the ring and took out Corbin before signing the contract himself.

Although Cena lost his championship match against Reigns, Balor hasn't forgotten that the Leader of the Cenation stripped him of his opportunity to face Reigns at SummerSlam. In an interview with The Mirror, the Irish superstar expressed his desire to face Cena at WrestleMania.
"I can’t think of a better place to face John Cena than at WrestleMania. I’ve got a bone to pick with John, the SummerSlam main event was mine, my name was printed on the contract, however, John signed it. There’s certainly an issue that needs to be settled between me and John and, if we can do that at WrestleMania, all the better," Balor said.
Balor and Cena have shared the ring a few times in the past few years. However, they only went one-on-one once in January 2018 on RAW, in which Cena came out victorious.
