Looking at the first match, Moreno's football style is like the Red Bull school, so high work rate is essential.

‌
Today, with Oh Hyeon-gyu and Son Heung-min unable to defend,
and Lee Kang-in being a style that doesn't press, plus having Hwang In-beom stuck in the center,
there was no way the match would go well.
I don't know if Moreno failed to properly assess the players or what,
but it's understandable why Kim Min-jae is pissed off.
