It does need addressing, just not right now. Say we bring in a new manager with a completely different style of play and the players don't take to him and we keep dropping points, what then?
This needs looking at from top to botrom and bringing in a manager mid season isnt going to change anything.
Moyes,LvG, Jose, Ole, Rangnick, several managers.
Jose won the ECL & EL with Roma and Moyes won the ECL with West Ham so that negates your point they done achieve anything of note.
This football club has been in dire straights since SAF & Gill left, since then its been a plethora of blunders when it comes to structuring the club and the decision making process, sacking and hiring a manager mid season isn't going to change any of that.
He'll be sacked in the summer when a proper structure is put in place.
