Does Punk still have it?

I think AEW signing CM Punk is a great idea; the ticket sales for the Chicago show alone prove that. However, after seven years away and a disappointing MMA career, I wonder if Punk still has his motivation. Okay, he’s clearly going to have to be ready to get back on the road and take bumps so not shying away from that, although the money will naturally help (not that I’m criticising; if Khan wants to pay a fortune Punk should take it). But Punk has been away from the biz for a while; will he still have his pro wrestling mojo?
