Potter was asked in a pre-match Brighton press conference about the speculation. He's hardly going to turn around the day before they play Chelsea and say "Yes, I'd love the job" is he now?
Any managers in a job, it's guaranteed the press will report on any official approaches to the clubs in question.
As

This is not a, nor the definitive list of candidates. It's pieced together from bits that have been disclosed to the press, fan speculation and lazy clickbait journalism.
