Debt
If a team goes into debt, they cannot bid for players on the transfer market or invest in the academies until their balance becomes positive again.
When the weekly financial update is performed, if your youth or senior academy investment amounts would cause you to have a negative bank balance, the amounts are adjusted down, starting with the senior investment amount.
For example, lets say you have your senior and youth academy investment amounts set at $20,000 each. The financial update runs and calculates that if these amounts are applied your balance will be -$5,000. The game then adjusts your senior investment amount down to $15,000 for the week
By the way, what would happen if i get -ve balance? Would i get bankrupt or something
Bidding on Your Own Players
Managers are allowed to bid on their own players. We understand that sometimes managers list a player and then decide they want to keep the transfer listed player.
However, some measures have been put in place to discourage the practice of managers attempting to create a phoney 'bidding war' by bidding on their own player to try and drive up the price.
* Managers can bid on their own player, but they can only do so once. If you genuinely want to 'buy back' your player, make sure you bid your maximum bid, as you will have no further bidding opportunities. This mechanism has been put in place to give managers who genuinely mistakenly list a player the opportunity to buy them back.
* If you bid on your own player and end up making the highest bid, the 'number of days in squad' counter is reset to zero. This means that if you immediately relist and sell the player, you will only receive 50% of the transfer proceeds (see the Transfer Settlement section above for further details).
