Hello, maybe not a bug, 1st time I've tried this home team sponsor, I certainly didn't understand the concept.
At the moment I have 0% sponsor development, yet several players from my cdf have played in the 1st round of the championship.
Any explanation please? Thank you

You have to play 32 matches a season with at least 8 players from your youth academy

All 8 players must be on the pitch at the same time?
I'm not sure it was 32 matches, because unless I'm mistaken, we're talking about competitive matches, and there aren't 32 competitive matches in a season?

32 matches in all competitions.
As for the rest, I've never tested it because I've always lined the players up at the same time from the start of the match.

You need 8 players from the CDG AND they have to play at least 20 minutes for it to work
In addition, you have to try to keep them until the end of the sponsorship (having received the money)
I always take this sponsor 👍

OK, I've got 8 players here from my cdf, haven't I?
8 players with the house, they have all played matches this season, 1 match out of 2 each, so much more than the 20 minutes. Why am I still at 0% evolution?

They have to play together for at least 10 minutes, then during the match you can change players
But you must always have at least 8 cdf players in the match
And as soon as you have taken out players due to cdf

Rull43: Ok j'ai bien 8 joueurs ici de mon cdf non?
8 joueurs avec la maison, ils ont tous joué des matchs cette saison, 1 match sur 2 chacun, donc bien plus que les 20 minutes. Pk suis je tjs a 0% d'évolution?

Probably because the season isn't over and it will be updated on the last day or when the new season starts

You need 8 players from your CDD on the pitch at the same time. If, for example, you have 6 one day and 6 the next, it doesn't work.

It updates immediately

So they didn't play together. Never mind, we're learning.
Thanks for your feedback. We can close now. Thank you
