Son Heung-min needs to be taken out of full-time play

It is still true that he is the best domestic player, but he just doesn't have the stamina anymore.
I think it would be better if he used all his strength in short bursts.
If Son Heung-min, Lee Kang-in, and Hwang Hee-chan all play together, the defense is hopeless.
We should give more opportunities to young, fast, and high-work-rate players on the wings, where we have the most resources in Korea.
It also seems better not to use Lee Kang-in on the wing for the national team.
Both players are the best in Korea, but it feels like the team is struggling because of them.
