And to show how easy it is to misread a PKM:
Rash said you should have pushed the d-line higher. In the Attack formation it is set to 17. I personally think that is the major problem people come up against managing top-class sides. A d-line of 17 works with an attacking mentality setup until a certain reputation level. Once you get that far, you begin to play against very defensive setups that rely on the quick break. a deep d-line does two things:
a) protects the defence from the man getting behind them
b) opens space around the pitch.
What is a weakness at lower levels is a requirement at higher ones.
