Hilariously, I'm in my final year of a business analytics and finance major, and Dr gonzo is an actuary. We have forgotten more about databasing than you will ever know. But this really isn't a question of databasing.
Liverpool will have a shortlist, on that list will be 1 or 2 managers that they desperately want, and 2 or 3 that they will fall back on if their first pick can't be made available. It's not some list of 30 managers that they're going to watch footage of, compare performances and interview. They know who they want.
