Im still playing with the old market, thankfully. Heard bad things about the new one.

In the old market, there are times that there are low quality players (no 5 stars). But this rarely happens. Waiting 3 hours for your player to get sold is not so bad. Im guessing you need the cash for player purchase. Just list him and leave the game and get on with your life. Log in back and Im pretty sure your options in the market will be more or less the same or better.
