#4 CM Punk
WWE is very much in the business of desperately trying to get the fans to love Roman Reigns as much as Vince McMahon does. They've tried so many different things to earn that love over the past few years and no matter what they do, the majority of the WWE Universe continues to reject him.
One of the company's favourite things to do is put Roman alongside a Superstar who always gets cheered. They did it with The Rock after Reigns won the Royal Rumble and it failed miserably, plus they've tried it briefly since Seth Rollins returned from his injury in 2016.
At this point it feels like the only man WWE could align Roman Reigns with and actually see him get cheered is a returning CM Punk. Not likely, but it was comments that Punk made about Reigns that got fans hating him so much in the first place.
