Mike, I think what your talking about comes down to one word. Loyalty. That is, knowing how you got to where you are, and knowing who helped you along the way.
Unfortunatly there is very little of that left in football (in life as well unfortunatly). Its turned into a business, which I don't have a problem with, but it has taken away something that was at the center of the idea of a Football Club. The likes of a Scholes, or a Giggs are rare these days. At Liverpool I think we've been lucky, and I'd consider Carra, and Gerrard (although he flirted with Chelsea) loyal, but beyond that most statements of loyalty to the club are just words.
In Barry's case I don't know how much the Villa fans should expect in terms of Loyalty. Yes you made him the player he is now, but he's not a local lad, or even a product of your academy. He's also got to decide what's most important to him. Playing for a club he can call home, reaching the highest level he can in his proffession, or making more money. At the end of the day, that question can only be answered by Barry himself, and individual Villa fans. Therefore I take myself out of that discussion, its beyond my area of expertise.
