In terms of the type of manager, I would prefer someone who has experienced what elite level football is like in recent years rather than a journeyman manager who has spent a career moving around L1 and Championship clubs.
I look at some of the names discussed and see people who have not stayed anywhere for long and not succeeded in anything notable.
I don't want a Frank Lampard, but someone that generates at least a bit of excitement and respect amongst the squad at the prospect and has more than just a list of clubs and Manager of the Month awards.
We had a manager in Nige who had that elite level experience and need to replace him, like for like.
