Yeah refusing to sign them doesn't put them as a FA on the transfer market. They get lost foerever. Most likely they are sobbing that their local club didn't think enough of them to pay them a real contract.
So yeah I challenge Joshiko to show me a 18 year old that he has bought as a free agent considering the player has never signed a contract in the first place. High value Noerdgens yes, academy unsigned rejects, no.
