A little tip for new managers level 1-2.
If you have tokens that you need to exchange for cash to buy players for next season, if you win promotion wait!.
25 tokens at level 2 gets you 3m and 6m at level three, the same applies with level 1-2 it doubles if I remember correctly.
OK you may miss a few days of the transfers between the season but the difference is self explanatory, wait until you manager rating goes up.
