Some thoughts, maybe bollocks? For all his outward show of bravura and bravado, even arrogance, I reckon Enzo is actually lacking in confidence. When his idea was working with results, he could easily hide that. When it started to fall apart, he actually started questioning himself and didn't like others doing it, hence his "I'll walk" proclamation. That inner fragility means he is actually afraid to change or is catatonic to do so. Our players now look scared in games to do anything different and that fear comes from Enzo's lack of confidence.
