oh please... Look through the players we've had and what they've been involved in, look at what our clubs been involved in continuously since the 1920's... Its complete hocum...
and, no its not different to anyother teams 'material'
Let us give the example of Boumsong. Before Boumsong arrived many said he's not Juve material. Now he's considered a good defender who is yet to improve, but he's not poor otherwise Juve wouldn't have got him.
Is a juve player at the end of a match turning his back to the juve fans and wrapping the opponents scarf round his neck a sign of class... is that indeed...'Juve material' ???
