It is the midfield of the pitch where statistically games are played out, won and lost. All good teams have perfect blend of graft and guile.
It's amazing to think that the board didn't understand that a couple of injuries would seriously weaken this side:
Wharton: Injured, needing surgery, yet still played
Eze: Injury prone, blows hot and cold, goes missing during games
Doucoure: Recovering from serious injury, not ready for the rigours of his particular game
Schlupp: Rarely injured, but chronically unfit for the demands of the midfield
Hughes: Suspended. His game play will lead to suspension on occasion
Kamada: Rubbish in midfield, but he's not a midfielder
Lerma: Injured. Another grafter missing.
To conclude - all grafters missing or injured, players with guile injured. Calling for Glasner's head won't make any difference. The new guy will have exactly the same problem trying to put together a vaguely functional side, until the injured are recovered and up to speed.
