I'm going to keep this summary super general, but basically the comment or article was comparing two european countries and their soccer players. The author explained the discrepancy in skill in terms of how effective the country was able to identify individuals with potential/talent, and direct them towards the right path.
If you could help me find this article, I will forever be indebted to you.
hi! this doesn't sound like a topic that would've been in this sub. Maybe try x-posting to /r/soccer and/or /r/football: they seem more likely, and even if the article wasn't posted there, someone there may remember seeing it
