At level 29 its impossible for me to sell anyone.
I've listed players over 800 times this season without a single bite. Still trying today, as I want to bring new players in for level 30 in the morning, but I only have 2 free spots in my team as it stands.
If I can't get buyers today or tomorrow then I simply won't use my tokens until the following season when I can release my current unneeded players for free and get new players at level 31.
Nordeus really need to come up with a solution to get rid of un-wanted players higher up, as its stopping people from using tokens - thus it will cost them as people wont buy them as much, as I refuse to sack a player for around 80M just to bring a new one in.
The money issue higher up has crippled the game. You either have enough game money and tokens and can buy who you want (but then you can't sell anyone as no one is able to buy), or you have no money and cant buy anyone. Its stupid that we can't set either a really low selling price, or have an auto sell function - or even an option to free list the player. I notice the game is able to sell players with no problem when they bail a side out for being bankrupt for over a week, so I can't see why they cant put the same function in to help those that want to rid their teams of rubbish.
