limit player without contract

[Eric Perromat]

hi all,
is it possible to limit the number of player in club or is it always limited ?
11 players
7 Seat
4 Reserve
and after the player havent not yet contract for 7 days or reduce at one day ....
Is it possible to limit this because some players abuse they buy all free agent player (one exemple today a same person buy 12 players, yesterday the same things and so on ... He has plenty of token ....)
thanks for your response ...

Edit : only 15 minutes ... 3 players buys with 20 tokens ... And it is allways this all the day ... He has only one "place" in s team and i suppose he has 10 players or more without contract !
