You'll not be to blame gru! Whatever happens on the pitch you'll not be to blame son! The one thing about being a supporter from the sideline without any responsibilty at all is none of us will be to blame.
The difference is, most won't predict doom so that one day they can gloat from their front rooms, bar or even at the match that they got it right and someone else didn't! Yet it's that someone up there making the decisions whilst the rest of us sit and support what they're doing or not. Those that are not are waiting for that failure to bappen so that they can say that they were right.
Enjoy as much of the game as you can mate.
