Star player losing form

[Tactician]

For curiosity, did this happened after a new player signing? or you still having same team and this was all of sudden?

Suppose that a new player was bought and signed, even if the new player does not have any same positions with the affected player, what do you suggest, to sell him or sell someone else? This is negative playing. I understand that there is this possibility of a reshuffle of hidden roles in a team after a new player is bought, but then if so, what, the user never buys a new player again in fear a bad reshuffle could happen? Negative playing again. This is a part in the game that needs improvement if ever there are such things.
