What I have seen this season on the pitch seems to mirror what the stats suggest, we have had rotten luck this season, with a lot of goals scored when the opposition have had few chances prior, and we've been wasteful in front of goal.
Look at Norwich away, 9/10 the guy doesn't score the equaliser, Cardiff's second during the home game springs to mind, the scorer is a bag of crock, he slices that wide 99/100.
I always concede though that, when thinking back anecdotally, I suspect a lot of supporters feel the same about their own team.
