Well, good question
I don't really know, think it's just random. I remember back when I was at lvl 1 and 2, I bought a lot of 5* +28/30 players and managed to sell a couple, while 1 or 2 o them desided to "retire". I just kicked them out of the club, simple as that
You could try, but don't count on making any good deals ($) since it's almost the end of the season and people aren't buying "oldies" anymore as before. That trick worked "fine" on lower lvl's.![]()
