I agree with most of your post, but just wanted to pick up on this. I think the kids signed in the last 12 months (Pacheo, Bruna, Nemeth, Dalla Valle etc) look to have much more potential than those Rafa brought in initially (El Zhar, Roque etc) and therefore they are more likely to be given a chance, albeit that they are still very young and we won't see them yet. The other point is that a large number of the initial kids were defenders who always take longer to mature and that may also play a part in their lack of appearances.
