What a backwards idea. They were the best footballers of their time... Now, would they keep up? probably not. It's also elitist to pick rep teams like that and does exactly what everyone is always complaining about football being like.
Judging by the Socceroos its working better then maybe people are willing to let on. It takes more work to get there not less - the AIS and support systems around footballers needs to increase not be removed.
