because La Masia hasn't developed a defender since.... well, since Puyol... and the midfield talent Barca had their hopes pinned on (Thiago) left for pastures anew when it was apparent he wouldn't be given the chance to show his worth from a starting position... a luxury that was fully afforded to his seniors, back in their day....
but the trend is apparent... for all the "stopgap" theory barca faithfuls might like to cook up, aside from the current crop of La Masia graduates (Xavi, Iniesta, Puyol, Busquets, Pedro, Mess [sue me if i'm forgetting someone]), Barca haven't really developed someone ready to take the team by storm.... one has to wonder whether the new graduates this season can stamp their authority.... so far, Luis Enrique's attitude seems to be leaning on him using these young players more, but with the marquee signings that Barca have made, i don't really understand who these players will actually replace.
