i've just renewed my sponsorship but every season it only decreases by 100 k but I never see it reversed and club and seasonal sponsorship increases

Mine has increased between this season and last

It's linked to your index: the higher your index, the more generous the sponsor.
This season, I took on my sponsor as an index 8 and the amounts are higher than last season when I was index 7.

no, I've moved up from index 7 to 8 and despite that I see a 300k reduction compared to last season for championship sponsors

last season I was 53rd and now I'm 46th, but there's always a drop, or that too is random on vf

Did you achieve your sponsor's objectives last season?

no I lost the title at the last game even though I was unbeaten but before with the sponsors of goals scored, I always succeeded and yet the sponsors are only decreasing it's 100k or 300k max but it's going down

VALENCIANO: non je perd le titre a la dernier jouer malgre que je suis invincu mais avant avec les sponsors de buts marquer, je l'ai toujours reussi et pourtant le sponsors ne fait que diminuer c'est 100k ou 300k max mais ca descend

That's inflation for you ^^

That must be where it comes from.
I've been successfully sponsoring for two seasons now and the amounts are only increasing.

I've seen an increase when I win a championship, which brings me supporters, so when I have more supporters than the season before, the sponsors increase slightly, and when I have fewer supporters than the season before, the sponsor drops slightly. So maybe it has something to do with the number of supporters.

An excellent comment. Thank you very much.
