This is where 'we' (club) need to be patient, if the kid is too good for serie C and was sent to a club which didn't play him then we should pull him out early or choose a less pressured environment i.e a serie B team that is tactically setup for these players, and fighting for survival or a midtable team.
'Our' choices contribute to how the players develop. Its just recognising signs early and knowing where the player could grow. If a club doesnt play our youths more than 5-10 games before december then we dont loan to that club. I'ts difficult of course because the flip side is imagine loaning huijsen out to pescara rather than Roma. Usual case by case basis thorough understanding of where the player actually is. Timing is everything. Getting this right is important otherwise we will see more examples of Correira or Huijsens sliding through our fingers. Im not saying its not possible to make mistakes its just some teams do less than others and actually have the experience and know-how to do this. If we need to recruit/poach staff from sporting, benfica, lille, dortmund, ajax etc, then we absolutely should.
With all that said, im pleased with the progress we've made over the last 5 years, but we can now take this one level higher.
