In my experience the 30 year old won't sell, the younger ones have a chance but it all depends on their star rating. A 4 or 9 may sell but a 0 or 5 will be difficult to sell until people are desperate on either day 28 or day 1 of the new season. I have a team on level 30 and cannot sell an 18 yr old star rating 149. No easy transfer markets now on T11. T11 appear to want you to buy tokens to get cash from the bank and not from transfers. More money for T11.
