I think a formula could be generated so that seasonal objectives are challenging enough for each club.
For managers who are against this, how about this:
We allow managers to choose before the new season simulation if they want to be set objectives by the club's board for the upcoming season and how many objectives they want set. If they don't then fine, they can't earn or lose money/manager points as normal but if they do then they can. There could be a certain randomness about the objective setting to make it more fun and a little less unpredictable.
If the manager reaches an objective set at the end of a season (next season simulation) then they are awarded money and manager points (the amount of which an objetive is worth would be clarified in the objective chart).
There is also the risk of losing that money and manager points however, if you don't complete the objective.
I really am beginning to like this idea (even though it is mine!) and honestly think it would make SoccerProject even more unique and fun to play.
There could be a limit for the toughness of an objective depending on the team rating or whatever (or division) but the random factor could determine how tough the objetive would be under the limit.
THIS IS NOW NOT A SPFA FEATURE BUT A NEW GAME FEATURE IDEA. This would make it fair for everyone.
"Can you manage it?" - Can you reach your objectives?
The chart could look like this but with the new idea doesn't need to include the almost column:
