Noisy players should just retire quickly

Let's just go through a generational shift once and for all.
If you have players like Kim Min-jae or Hwang Hee-chan who express so much dissatisfaction,
they end up influencing the younger players; it doesn't help the team's strength, it's actually a negative.
If we keep using new players, we'll discover someone like Park Ji-sung.
We need to let go of those "useless but still used" players who openly express their discontent...
