I will try to be friendly about this.
I agree you may have some financial instability. That would likely be due to not working on your arena. However, if you have not been spending money on players, and not improving your arena, where were you spending money? Having 24 weeks to be under the salary floor should have given you the opportunity to improve your arena.
However, if you are going to spend to get up to the floor, and you already have trainees, you may want to search the market for older players as you can acquire the salary without paying large bids to acquire them.
