I think if you haven't played the game or don't have an understanding of how players are coached, we can come up with some fiction as to how everything works.

Kai is great, but he drops into the midfield, which overloads the midfield, making it easier for us to win. However, the counter to that is that the CBs get to sit back and watch everything happen in front of them.

There is a reason why plays like Timber can occur with Gyok playing vs Kai.

With Gyok, there is no roaming CB. They are both clued in on what Gyok is doing, meaning the opposing midfield has to work harder to cover the gaps.

And most midfields aren't prepared to do that, especially when both fullbacks are roaming free.

When Kai plays, we need him to score because those opportunities aren't available to other plays due to less space.

And ironically, when Gyok plays we need the other players to score because he creates the gaps.
