Asked if he wanted to one day manage Palace, Popovic told Sky Sports: "I'd never rule anything out.
"It's hard to do that in management. It's not really a job with job security.
"It's something I enjoy and you never know where it will take you. I want to be the best I can be as a manager - as I was as a player.
"If that took me on a path that included England, I'd certainly enjoy that."
