#1 WWE Champion Kofi Kingston

Now here is where things get interesting.
When CM Punk left WWE in 2014, the New Day was not even a thing, and Kofi Kingston was a generic, though popular, mid-card babyface.

In 2019 though, Kingston and the New Day are one of the most beloved parts of WWE, with the Ghanian Superstar riding high as WWE Champion.
Obviously, this would be one of the most difficult matches to arrange, given Punk's disdain for the WWE.
With that said though, Kofi and Punk are long-time friends, and the Chicago Made star has even said how much he loves the New Day, despite not being a follower of WWE content.
What better way than to give his old friend the spotlight, than returning to the company and feuding with the bastion of positivity.
