Just from what I saw today and against Liverpool, it's mostly the players.
Yes, the manager is important and the buck stops with him. I usually agree with that. But the AVFC players didn't even look arsed today. The manager can scream all he wants, but if the players don't care, there's nothing he can do. He can't give them a winning desire, they're supposed to possess that by wearing the shirt.
Villa fans deserve better than that.
