It is a good idea to invest maximum in your youth squad, because it pays off, sooner or later.
The best is to invest like this:
- 5.000 euro's until you hit inadequate
- 10.000 euro's until you hit passable
- 20.000 euro's forever
Once you start lowering your investments in the youth squad the quality will drop and it will take longer to get it back to the previous level.
