if your level for 5 star player`s is 179 then they need too be 1 skill point away from 6 star to go on neg list and as you are high level you can sell 4 and 3 star player`s as long as they are 1 skill point away from next star, it`s just waiting for bids too come in and with the blue on neg list they are not free they are player`s from your friends list
