Once you reach maximum level in the youth academy, you get 2 young players every 13 days or so. One of them you can sign for free (no tokens cost). He sucks, but at least it's free. The second player sucks as well, not as much, but it's still a reserve player, not even for the bench. However this second one is not for free, you have to pay tokens for it. I wonder if there's anyone who actually pays for it.
I personally think it would be a very nice feature if at least one of these players was worth the price, or at least if they were any useful. Every time I get them I fire the costly one and hire the other one for free just to sell it or to get more training points. Otherwise the academy and the players that come from it are simply useless, at least for my team.
