The current excuse is that the players lack confidence - a nonsensical excuse
The players who succeed and are valued are those who keep themselves fully committed, irrespective of what has happened, or is happening. Go back to players like Holland and you will see the difference.
Unfortunately these kind of players cost, for the obvious reasons. And despite the talk of multi pound signings much of the squad are those from Cook's address book. Just as the coaching staff are.
And many of the signings are no better, than what Cook inherited. And Hladky is certainly worse, hence Walton.
Heaven help whoever eventually inherits this squad.
