Apparently you missed the 07-08 season for a start. Fletcher was squeezed out of the first team picture by the arrival of Anderson and, particularly, Hargreaves. As I said before, without Hargreaves' injury, there's no reason to suppose that he would have found a way back in.
Forlan, Kleberson and Veron all went because they didn't establish themselves at the club. The simple fact is that Anderson did establish himself. Now, while I'm sure that you're a better judge of talent than SAF, it's hard to deny that Anderson's continued presence (plus the new contract) suggest that the club sees something in him.
When did this happen?
And why are you taking cheap pot shots with the better judge than Fergie stuff? No need for that I was enjoying the debate but if thats the line you're going down then I'll stop here.
