how will he be letting us down?, his loyalty is to himself and to money, next season he will be where-ever the best deal for james milner is, if that is away from villa then so be it, he is a self employed professional footballer, and will always chase the best contract, its not letting anyone down, its just the way it is
How would he be letting us down?
Do you not think that he owes us more than 1 good season since we payed over the odds to resurrect his career, helping him to become one of Englands most established players?
Personally, I think he does.
paying over the odds, and possibly selling for way over the odds, football is a business, the clubs are here to make money, you may not like that but thems the facts, players come and go, the villa remains the constant, if he goes, he goes, no amount of moaning/whingeing/whining on the interweb is going to do anything about it, best to remember how good he was while he was here than get all worked up about him leaving.
