The two teams I wanted to see most before the tournament started, both delivered well.
Aye same, I'm fascinated by how the Chile system works. They seem to be able to throw players forward in wild abandon yet look fluid enough for others to fill in defensively at the same time, it's a joy to behold to see such a dynamic system working. Of coure though, we'll see how it works against Spain and even Switzerland.
North Korea is just sheer intrigue, and they're the ultimate quirky underdog. Come on you plucky axis of evil.
Be interesting to see how their system holds up versus Spain although it might end up being a dead rubber IIRC which would be a shame. The Chilean players seem to have the drive/fitness that the Argentines didn't when Bielsa tried that system with them in 2002. I think it helps they have a lot of adaptable players too. Sanchez can play anyhwere upfront as can Mati Fernandez, Medel can play any defensive position.
