NOBODY can judge whether or not ANY academy player is going to join the first team or not. There are 4-5 great talents in all Masia teams with the ability to go far one day.
Juvenil A: Lee, Cucu, Busquets, Mboula, Ruiz.
Juvenil B: Miranda, Jaume, Orellana, Riqui, Gomez.
Cadet A: Tenas, Garcia, Nico, Bernabe, Ansu, Moreno.
Cadet B: Domenech, Navarro, Rico, Abaida, Jardi.
Infantil A: Simons, Olle, Pelaz, Alastuey, Balde, Fermin.
Infantil B: Almeida, Larios, Garrido, Capdevilla, Paez, Planas.
On the surface, these are the highest rated talents of La Masia today, but nobody can predict who and how many of them becomes first team players.
Many times it's the less known players on the teams who go far, like Puyol, Pedro, Busquets, Roberto. Puyol was always told he'd never make it, Pedro was behind several wingers when he joined Juvenil A, Busquets wasn't hyped at all during youth years before Pep joined Barça B, and Roberto was usually a squad player in his younger days.
