Beckham, Neville, Butt and Scholes are not young, you say? I had no idea.
Or are you talking about Campbell, Gibson, Wellbeck, Eckersley, Martin?
If those Arsenal players you mention get 10 games, great, but you really can't guarentee that. The point is, based on the traditions of the clubs, United, and probably West Ham and Villa represent the best opportunity for domestic talent.
