I think that has something to do with it. I was interested to hear on TalkSport recently from England fans who are going to the match this week - nearly all are going because it is their opportunity to boo and let the team know exactly how they feel about the World Cup. Sounds daft at first but as they said it is the only way they can let Capello and the rest know their feelings.
As for O'Neill, he is obviously a very ambitious man and when every breaking Villa story is a player on the way out, you know things aren't going well. A huge mistake to let him go.
