Interesting video about how "we must build from the back" doesn't seem to be working any more because of the high press on the pro level. Particularly focusing on how it doesn't seem to be working for Onana. The high press seems to be resulting in errors resulting in easy goals against. The prescription on the pro level seems to be that teams need to be able to adapt on the fly.
I'm not sure it ultimately changes things on the youth level because while it's easier to learn to go long it's quite a bit harder to learn to build from the back, and if you don't learn it you won't be able to do it. The US at the academies at least emphasizes a US academy style play where they should learn to build from the back but have some freedom to go long if need to be. Where I do think the US education is deficient is when it comes to goal kicks. Firstly, at the young ages too often still the goalkicks are given to the big legged defenders. And even when they are older there is very little by way of tactical training about how the goalkeeper needs to make the decision to go short or long (to the extent goalkicks are practiced, it's usually short, so the team can have the benefit of practicing building).
