#1 teasing a potential rematch against The Undertaker at WrestleMania 35
One exciting option for John Cena in the Royal Rumble match could be to tease a potential rematch against The Undertaker at WrestleMania 35, which is expected to be the retirement match of the Deadman.
As of now, the Deadman is 53 years of age, and has not much left in him. In fact, his last match at WWE Crown Jewel where he teamed up with his brother of destruction, Kane, to take on the duo of HHH and Shawn Michaels was also underwhelming.
So WrestleMania 35 could be and should be the last outing of The Undertaker, and who better than arguably the greatest WWE performer of all time in John Cena to go against in your last outing?
Creative could have The Phenom enter the Rumble match as a surprise entrant, and get involved in a confrontation with Cena, laying down the bread-crumbs for a potential rematch at WrestleMania 35.
