Thiago would make it but he was impatient.
While that's true our management the past two years never showed faith on Masia players.They were rarely used and only called up when there was no other choice.Tito overplayed Xavi instead of Thiago,Alves over Montoya and even used Adriano as CB over Bartra.And with Tata nothing seems to have change drastically.Roberto was given few chances,Bartra was called up when there were injuries and Montoya was rarely used.
Montoya is a great example.Imo he isn't the best RB in the world but neither is Carvajal.The latter was implemented in the first team while the first still is labelled as youth player..
At the moment i can't really blame any Masia player if he wants to leave.Our managers tend to trust only big money transfers (Cesc,Aexis,Neymar) and veterans (Xavi,Alves,Puyol) and forget what one of the reasons that made Barca great the last decade.
