i build relationships with players on levels below me and am happy to release players for fair token offers if they are in a position of need. I sold a GK with one on one to my most consistent customer for one token 5 days ago and sold him my current league leading scorer (who is underleveled at 64Q in a 74Q league today for 7T. He was having trouble scoring goals and had a **** keeper and he has bid double digit tokens for my players in the past.
If you don't have the patience for creatng your own feeder clubs, identify small token buyers lower than you and build relationships. I like seeing my trained youngsters smash other leagues after their training slows down/get outlvled by promotion. Making an extra 20-40 tokens a season on negos helps too.
