I think it's Rafa's idea to integrate ALL of the youngsters (no matter how young they are) into the Reserves whilst giving the likes of Hamann, Morientes etc a rest (when he can). We have a massive number of games to play this year and I think Rafa's plan is to have a steady pipeline of youngsters pushing for the 1st team in seasons to come rather than have to spend massive amounts of money. I think we can all see that Rafa has a certain kind of player he wants to fit with his style of play. It's clear from our inactivity in the transfer market that there are not many top class players who fit that profile. I reckon buying the youngsters at 16-19 will allow him to mould them into the players he would like them to be. It's a similar approach to that of Arsenal with Fabregas etc. Rafa is here for the long-term and, for that very reason, he is planning medium-long term.
I trust Rafa!!
