Fans and sponsors
Your fans and sponsors are important sources of income for the team. Therefore it is strongly advised to keep good relations with them and to keep their mood up - it will pay off in the end.
The members of your fan club decide a lot when it comes to your team's finances. Membership fees (30 US$ / member) are paid once per season, but more importantly, their mood helps determine attendance, which affects gate receipts at your stadium.
The easiest way to keep their mood up, and attract new fans, is to match (or even exceed) their expectations. Their current mood can be seen on the Fans page.
At the start of every season, fans will tell you what they expect of the team. These expectations depend mostly on what happened last season, what fans expected then, and what the outcome was.
As your team advances (or drops) through the league system, your fans will slowly get used to the new situation. If you just got promoted, fans will not expect much. But if you are staying put in the same division year after year, fans will tend to hope for just a little more.
The season expectations influence the expectations the fans have for each game. On the Fans page you can see what they expect from each game. Generally, fans expect more from you when you play at home.
If the match result is what they expected, a win will make them like you and a loss will not disappoint them too much (if they were predicting defeat). If the result is better than their expectations, their mood will be even better. But if the result is worse than their expectations, it will affect their mood negatively. For the first league rounds of the season, your fans' reaction to the results will be a bit more moderate.
At the start of the season, match expectations are based on the seasonal expectations of both teams' fans. As the season progresses, the actual league standings (position and points) of both teams becomes more important. In cup matches, fans base their match expectations only on the seasonal expectations (including division level) of both teams.
Team attitude and your cash funds influence fans
Telling your players to "Play it cool" or play the "Match of the Season" also influences the fan reaction to the match result. If the result is as expected (or better), playing it cool will reduce the positive effect and match of the season will increase the positive effect.
If the result is worse than expected, playing it cool will increase the negative effect and match of the season will reduce the negative effect.
If you have a lot of money saved up, your fans are a bit harder to please as they feel you could be spending to reach success. Rich teams' fans react more harshly to losses and less positively to wins than fans of poorer clubs. The more money your team has, the higher the effect.
Sponsors prefer to support a club with a good image. As your team finds success, and as fans join your fan club, your team's image will improve, and so will income from sponsors. Your sponsors' mood can be seen on the Finances page.
