Just my 2 cents
I guess everybody has experienced this trouble - your club
manager says that he has halted the transfer of <player>
Usually it happens when you do not have many players (i.e. no reserve team at all)
But you can always sell out players, no matter how important and cool they are, in pre-season.
I manage my Forest Green in Division 1 and, after having very tough previous season, I need money. But I CAN NOT sell anybody.
I have purchased a number of old players (to avoid any possible limitations) but still can not sell.
I have loaned in two very nice guys - but still can not sell.
Can anybody tell me - what are the requirements for selling playes? Or is it a bug?

By the way - very nice tip
Loan in 17 years old players - choose the best available
Their progress is prominent - up to 20 skill points for 1-2 months, I guess. But do not forget to hire the best coaches, first.

You must have a FULL first team squad on the left side of the screen.This squad must not include any loan,transfer listed or injured players.I believe u may have to have a couple more as well(to allow for old player retiring at end of season and/or Bosman)

Thanks, Chivster!
It works
I guess you are right - I need 2 more players to be able to sell anybody in addition to the requirements you've mentioned
