On this week's episode of Monday Night Raw, WWE Champion CM Punk was granted permission by Raw GM AJ Lee to choose his next No. 1 contender.
Punk revealed that his pick was John Cena, but that was on one condition: Cena had to admit that Punk was "the best in the world."
Cena didn't do that, though, so we're left without a No. 1 contender for the WWE title.
Although I think we can all see where this is headed, it's worth considering all of the possible options for Punk to feud with in the coming months.
He's already faced a number of the WWE's top stars throughout his current WWE Championship reign, but that are still plenty of opponents he can face in the not-so-distant future.
But who deserves to step up and challenge Punk?
Well, here are seven superstars who deserve a shot at CM Punk and his WWE Championship.
