It was a bs report from Korean media. I was right about the age restrictions: only players born after 1.1.1997 are allowed, minus wild cards. That means from this year's U23, only KJM, LSM, KJY and CYM are allowed. LSW too but he won't get released. Maybe those 4 minus LSM (unless he can gain pt and become a better player), can get into the squad despite already being exempted.
