One more thing is, B team player are still benefit from coaches at my first team. As soon as they're able to participate in the lowest division available on the game, the specialty coaches don't give them any benefit.
Some team in Spain/Portugal/Dutch/Belgium/etc can participate on the league system. I really like that cause it gives young player a taste of real competition be like.
