I don't know if you guys can add a system whereby a player you wish to keep but because of some present conditions you have to sell. As in real life situation where a club sell a player but add a first re-sign clause into the contract i.e. whenever his new club wants to sell him, his former club will have the right of first refusal i.e. to sign him first. Don't really know if its possible but I think it will really make the game more fun and great. Thanks.
