What we need is a manager with imagination.
Someone to shake up who takes free kicks from different places on the field.
We need someone to show them how to take a throw-in usefully.
More than one way to set the field to receive a corner.
How to shape four or five defenders into holding a more or less straight line.
At the very least someone who can vary our attacking style.
If we could get a manager who can get players to swap their on-field positions during play...no, that's hoping for too much. The Dutch national team used to do it in the '70s but when Notts tried it it was called kick and rush.
All of these can be taught on the training field but will come naturally with experience, that is, experience of actually playing - you don't learn much sitting on a bench except how to get splinters out of your arse.
