In an All Elite Wrestling Post-Show Media Scrum last year, Punk spoke of his time at WWE and revealed the reasons he decided to leave it behind.
"I feel almost that the 10 years that I spent in WWE was wasted," he said.
"Because I feel it is Management, Owner, Booker, whoever's job, is to get the most out of all the talent. I feel that I never [reached my full potential].

Triple H took to social media to speak on Punk's return.
He claimed that if the WWE fans want his return, then that is what he will provide, adding that he and Punk are now different and have changed as people.
