Transfer options added in negotiations

Transfer negotiations on FC25 are okay but I believe EA you need add another option and that is to include a buy-back clause option as well because sometimes players who have stated unhappiness at not playing enough but are very talented end up having to be sold and then if I want to buy them back I have to do discuss on a whole new fee if I am to buy them back but I believe when we have to sell the player an option for a buy-back clause then allows us to agree on fee and I can have this option for 2 seasons then expires.
