I remember, when we played Sunderland in a similar situation, near the end of the season. It was the last game at Roker Park (under floodlights) and we won 0-1. Sunderland went down a couple of weeks later, and we stayed up.
Makes me laugh, this game could mean nothing, IF Wigan do not win tomorrow. Well nothing to us anyway.
Tell you what, I would not want this crowd on my back!
