5 potential challengers for the WWE Championship at Royal Rumble

#1 Sami Zayn

Could Sami step up?

Sami Zayn and A. J. Styles have yet to cross paths on Smackdown Live. However, out of all the options on the list, this could easily be the best match-up.

Perhaps Daniel Bryan can cause further tension at the top of Smackdown by putting Sami Zayn in a number one contender's match that he finds a way to win. This would further drive a wedge between Bryan and Shane while also giving Sami a chance to shine on one of the biggest stages. A win-win.

Kevin Owens vs Styles has happened one too many times this year so it could be time for the 'underdog from the underground' to step up and put on what could be an instant classic.

Although most title matches at the Rumble are fillers, there have been some real classics in the past years. This year could be one of those years.

If you have someone else in mind to go up against Styles, feel free to sound off in the comments below.
