It needs many factors. First, we have to get out of the relegation fight (which is a big possibility with the fixtures coming up) this season - with or without Benitez.
Then, there are many issues need fixing like recruitment policies, scouting process, medical and youth academy. Whoever responsible or appointed has to get those right especially on the recruitment part - we can't be signing 10 expensive players and only 2 worked out. The roles have to clear - the fans may not have to know, but behind the scenes; Moshiri must get it sorted out or get a temporary unbias advisor to find out all the issues and then is easier to get the board to fix them. I say temporary because seems like every permanent hire is trying to screw Moshiri in football matters.
