Son Heung-min is killing all of Lee Kang-in's strengths.

‌First of all, they aren't building the tactics around Lee Kang-in,
so why blame Lee Kang-in?
No matter how good an ace player is, if the tactics aren't built around them,
they can't perform to their full potential.
Even Messi can't perform at 100%
if the strategy isn't centered around him.
The national team needs to undergo a generational shift from Son Heung-min now.
Because of Son Heung-min, Lee Kang-in is being stifled,
so why blame Lee Kang-in?
They should give him the central spot in a 4-2-3-1 or a free role in a two-top formation,
but because of Son Heung-min, he's playing as a right winger for the national team.
The problem is there isn't even a proper poacher to match that lol
Just keep Son Heung-min on the bench;
bring him in at the 75th minute if they are losing,
or use him when a counterattack is needed against strong teams.
Otherwise, they should just let him retire.
Now the "Son-fans" are making a fuss again about "tempo" and whatnot,
but for the national team to recover right now,
there is no answer other than having Son Heung-min retire.
