All you can do at the moment is just hope a performance will come. One galvanising performance is all it takes, surely? West Ham got a point at Chelsea when everyone expected a drubbing - they've gone on a good run since. Norwich drew at home with City and went on to beat Spurs. And though I can't see Villa doing something like that at the moment, I couldn't see Norwich doing it three weeks ago.
Win this, hope results elsewhere go our way (as is standard these days), everyone gets a bit of a lift, and then maybe we can just safely see out another season to forget.
