#1 John Cena
So, I did not mention AJ Styles in this list because I think that he will be kept away from the title picture for some time now. I'm not mentioning Mustafa Ali as a possible contender because it's far too soon for him to get a title match at WrestleMania. Andrade 'Cien' Almas and Randy Orton are both heels, and so is Bryan. And so is Samoa Joe.
But then again, John Cena could certainly make a return to competition at WrestleMania 35 to take Bryan on. We all know that he could become a 17-time Champion at the said event. And if he does, he will overtake Ric Flair's long-standing record.
The very idea of this big match could help in selling a lot of WrestleMania 35 tickets. Cena vs. Bryan is a huge match.
Whom do you want to see Bryan face at WrestleMania 35?
