All season I've been playing my home team in friendlies and I've achieved 100%. But I've made a staff transfer with Ibarbo, the in-house MDC, and I've fallen to a 63% achievement rate.... I'm a bit embarrassed by this situation....

If you have sold / loaned a player before receiving the bonus
it's normal
You have to keep all the players until you receive the sponsorship bonus.

I'm with you on that one, but I've passed it on to the staff as an assistant coach... that's why I'm disgusted.
Too bad for me.

For your information, you can sell players who contribute to the sponsor's success. I sold almost all of them before the sponsor came to an end and they remained at 100%.
The problem here is the change from player to staff.
We'll see if this can be improved to avoid losing the sponsor.

I got screwed too, I reached 100% 2 days before the change of season, and today as if by magic I'm given 97% so the bonus is in the bag... disgusted with this game but excellent year to all
