The only way to save the national football team is...

By using Kim Min-jae as a defensive midfielder...
And instead of using fullbacks who are as useless as Seol Young-woo or Lee Tae-seok,
we should use wingers as fullbacks or wingbacks, give up on defense, and
go all-in on attack... I don't understand why we have to use Lee Tae-seok and Seol Young-woo
when they can't handle both offense and defense anyway.
Also, Son Heung-min and Lee Kang-in should be used as supersubs,
and we should rely on hard workers to win through high work rates.
