10 best candidates to win the Greatest Royal Rumble 

#9 John Cena

Will Big Match John live up to his name?

John Cena's recent feud and defeat to The Undertaker may go down as one of the most bizarre of his career, and taking a look back at Cena's time with the company, that is quite the statement to make.

Cena is the most established star in the business, so defeat to The Undertaker doesn't do him any damage, but a victory here would certainly help remind fans that Cena is still considered a massive star, and a potential title threat by the WWE.

While there is certainly an argument to be made that Cena doesn't need it, this one might simply come to business and name recognition. Cena is a worldwide star, and a victory for him would no doubt grab the headlines and seriously help the company crack their desired market.
