Excuses are running out for certain people.
I know some people knock him for being too loyal to players, but I see that as a strength, on the whole. How often do people say "we need stability" and then call for a mass clearout after a poor (well, OK - horrendous) display? That is exactly the lack of stability that has contributed to our problems in recent years.
On the other hand, you can't keep picking people who underperform all the time, and it's a tough call as to when you should eventually wield the axe.
Looks like Nobby is sharpening the blade... I just hope it gives some players the rocket up the backside they need. If performances improve significantly and consistently from now on, so much the better.
