1st, youth player - one will worth tokens that can be anything (tokens) if a player position you need and not to many tokens you could sign if not release, the second will be low and no tokens sign and put on transfer market ( free money )

2nd question, if player has skill point/points while on list no-one gains that but if he`s not sold and he stay`s then player still has skill point/points - this is why i add all skill pre selling
