System now has a default ‘quality requirement at a certain discount [minus clicks]’ for players to be sold within 3 hours or so. That is from observations of previous release, so please do correct me if I am wrong. The below is my experience just for your reference.
Some better 80%+ quality players would usually get sold by -2 clicks from max possible. Worse quality of 60%+ could take -4 clicks.
(2nd team) Had a 35% youth from YA cannot be even be sold with -5 clicks for 2 days and the player is back out from auction, and price of -6 clicks is just marginally more than the ‘sell now’ option, so I will train him hard until day 25 and try -5 again. If not sold, it is obvious that the auction option would not fit the low quality players from YA.
