I'm afraid I don't know who's on the shortlist, but having spoken at length with TB today (interview to be aired on Seagulls Player tomorrow) I am not expecting to see Dennis Wise appointed. His criteria suggests that it will be a manager or coach, with a fair amount of experience and an impressive CV, and it won't be an appointment from within.
It's very likely (almost certain) Hinsh, Steve and Charlie will be in charge this weekend, and possibly into next week and even beyond, as TB wants to make sure he gets the best possible candidate.
