What happens if u get into debts?

You pay interest over it.

So it will just get bigger and bigger but no point where action is taken by the board or something?

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.

Ok Thanks

How can I turn

Money £ 202 037

into

Construction costs £ 533 851

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...

Save THE money for it by selling players and budget cuts likje loper wages.
Or waait for tv revenue ;)

@Chrescerya

The shortest way to get money now is to wait the half season transfer market to open and sell a player.

look on tv revenue tab (for you, Chrescerya, it is here)

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)
