1- They can appear in three ways: in a random club, in "Other", and rarely as Free Agents.
This brings two situations: I don't know who was the dumbass that decided to create Others, when Free Agents would suffice and with much less confusion, but he was a genius compared to the fucker who decided that Others should be a fucking team. Which means, you have to pay transfer fees for them, but can't trade any players because they aren't in a fucking team. So, players in Others and in teams have to be payed wages and transfer fees. If they are Free Agents, obviously, you only have to pay them their salary.
One thing that happens quite frequently, but that is impossible to predict, is players that appeared in a random team get released. At least Howard regenerated this season and came in some south american team, and later in the Transfer Window he was in the Free Agents list. It's really gambling, you never know when this might happen.
2- I reckon the Youth Team only gets the worst players. No idea why, but I'm on season 4 and it remains like that.
3- PES stupidity once more. You have to pay a lot more over the Market Value for a player, even the regens in Others (right, they are soooo emotionally attached to being employed by no-fucking-one). There's no way no overcome that other than paying what they ask. But if the AI makes you an offer they will get that creepy green smiling face even if they offer way below the Market Value. I don't get it. No one gets it
