On your final para I agree. You shouldn't read anything into one-off results. It's over a period of games that you should be judged (Jason argues for a full season which seems fair to me although I maintain that you need to give a manager two seasons on the whole).
The 2nd half of this season will prove very interesting. The next immediate challenge is whether we can prove as effective at creating chances & keeping clean sheets when we come up against better midfields - time will tell.
