Under x4 and under x9 players: no one will buy them, no matter how good they are.
I've reached level 20 (21 now) and I can't sell players anymore. Been trying to sell players for over 30 days.
The players are excellent (7-8-9 rated), just not appropriate for current level. But no one will buy them because they are not at the brink of becoming 6*.
I list them 5 or 6 times a day. Nothing. Now a new season started, and they add up. I've 7 players on auction. Can't buy new ones, no room in team, no money in the bank.
I can't continue playing. This is ridiculous.
