You'd imagine there will be a structural change within the Football Department at the club, and the Head Coach will be a subordinate to the Head of Football. The Head of Football being on the panel deciding the coach would likely allude to this.
There were reasons this wasn't the case under the previous coach, but no reason for it to exist like that going forward.
Whilst the current occupant remains the Head of Football, replacing only the Head Coach is no longer going to improve the club's position.
