In order to succeed in making your team league and cup champions you must answer questions. You can't select your team but you can train them instead by answering questions. If you get the question correct then they improve, answer wrong and they get worse. To play a game against a team you have to answer questions as well. If they're attacking, get the question right and it's saved. Get it wrong and they score. Likewise if you are attacking, right means you score, wrong and it's saved.
