It doesn't matter what level you are.
First you try to sell the player with the max price.
Then, you try to sell the player by downgrade his value with one click down.
If you are not in a rush, keep try selling the player with the max value.
Selling or not is random. Hasn't any logic if the player is old or young, has more positions or sa, is near to a _9% quality.
The bots are buying anyway.
