It's not so easy to get into huge depts. You can't spend any money when your balance is negative and you'll still get the TV-revenue at the end of the season.
short term? cause my stadium (lvl2) isn't of big help...
I keep filling it up, had already 80%+ after construction and can't seem to get the money to level up from it...
You will get at least that amount of Euro at hte end of season (it depends on your points, so you get twice of that if you get 34 points at the end of season, and so on)
