but from my team lv15 there aren't for the last period , possibly because of "sell now" update.
Those are the cases that may we have free agents

Sacked Players -it's not exist any more with "sell now"
Released 2* or 4* Academy Team players - I don't think those are going to TM as free agents or else we would have many players (the 4* from 1 lv above, as 3* for us), and for all the levels
Free 2*-4* Academy Players that not signed within the 7 day period because manager wasn't present - I don't think they are going to free agents (same as previous).

Players whose contracts haven't been renewed within the first 7 days of the season -hmm, maybe but I 'm not sure.

Players acquired at auction/negs/scouts who haven't been signed within 7 days due to a lack of space in the roster. - not any more with the "sell now" app

Players that a manager lost because of the debit of the team. The team start loosing players because has a negative balance in finance -maybe that too. Now ith the "sell now" an active manager can sell at any time one player so to cover his debit.

So, in most of the cases the "sell now" option had as an effect the lack of free agents except the low levels. Too bad, as free agents was a good source of improving the finance. I hope and suggest that nordeus release the "sell now" players as free agents in the market.
