I like both Son Heung-min and Lee Kang-in, but the bashing of Son Heung-min is a bit much

At Lee Kang-in's age, Son Heung-min was constantly scoring goals and winning MOM in the incredibly tough EPL.
His best goals were also incredible.
Given Lee Kang-in's position, I don't think he can surpass Son Heung-min no matter how well he plays.
It is also uncertain whether a player who can perform at Son Heung-min's level will even emerge in the future.
