What sort of update would keep everyone happy though?
If there's a potential issue with the manager's previous club then any public announcement could prejudice the resolution of that issue.
If there's a potential issue with the preferred candidate himself then any public announcement could have an impact on our plan B, plan C, plan Z, etc.
If we're in negotiations with any party on any topic, it's usually best not to show your hand until those negotiations are concluded.
If we're looking for an announcement just to say we've made an announcement, people are still going to be pishing their pants over the vagueness of it.
There will be plenty of time and scope to hold people to account once the process is concluded and we get the full story, getting the pitchforks out and demanding speed takes priority is how we'll end up with someone like Robinson.
