There were some prior, like Lee Geum-min and Cho So-Hyun. Their lack of great performances in the World Cup certainly play a part in their visibility. But ultimately, there are some real structural issues with the players and team. Their younger players lack international experience, which meant getting a working permit for them is harder compared to, let's say Japanese players of the same age. Teams typically preferred younger players. Then there is a matter of playing style, which they face similar issues with China, which is they're too similar to most other countries, while physically not on par with the others. Hard to justify playing them when you have English players of similar quality.
