10. Bray Wyatt
WWE.com At the back end of 2013, CM Punk was putting to bed a feud against Paul Heyman with a victory over Ryback in a street fight on Raw and out of nowhere The Wyatts, as they have made a habit of doing, attacked Punk for seemingly no reason. This led to Punk joining forces with Daniel Bryan to take on Luke Harper and Erick Rowan in a tag-team match at Survivor Series, where they were victorious. Shortly after this, Punk entered a programme with The Shield, leaving Bryan to tackle The Wyatts on his own. With no clear conclusion to this rivalry, a Punk feud with the Wyatt Family does have potential to be revisited. The reason a one-on-one rivalry with Bray Wyatt has been suggested is because he wasnt involved in the match at Survivor Series, so the feud would be fresh, and since Punks departure and Brays rivalry with John Cena he has grown into a superstar on the cusp of the main event, more than worthy to take on Punk. This would be a relatively straight forward rivalry to book. The Wyatts seem to need no invitation to assault anyone, just as they did with John Cena prior to Wrestlemania and Chris Jericho most recently on Raw.
