La masia fails if one of two things aren't met
1) X youth player makes it to the first 18 and can be relied on to make even the slightest impacts I.E sergi roberto in lucho's first/second season or bartra before he was sold
2) we sell for profit like real madrid do.
we've failed so far with 1), our youngest youth players are deulofeu(23) and sergi roberto (25) with the only real prospect being carles alena and cucu who both still are unproven and not even in first team (samper, munir wanting to be sold and not depended on)
and we have failed with 2), in the last three summers we've sold off pedro, deulofeu, sandro, montoya, tello, and bartra all for a grand total of 45m€ (only counting la masia graduates)
to compare real madrid made almost double that number by just selling jese after huge injuries and morata not even counting the others like llorente or diaz
training failed kids our philosophy doesn't get us cash or trophies so who cares about that, call me ignorant i don't care but these are the facts.
