Hello, an ''A+ season'' is winning the league and all the cups you're in, A+ is for when you've hit the very top and are the best you can be. Fans can be upset at a defeat, the manor of a defeat etc. in isolation, that's fine as well.
Challenging for the league might be a bit harsh, but if you finish 4th with the extra income and drawing power then the board (especially if they're ambitious) will want you to keep progressing and pushing on.
We can look to see if we can do some fine tuning, but a board and fans will never being 100% happy, unless you go a season undefeated & win every competition you're in.
