Plot hole: The whole team went into the match, and the tournament, without knowing its rules. They all are totally surprised by the fact that the top 2 teams qualify from each group. Of course, that's quite impossible, especially since there are veterans in the team, Tsubasa is a football fanatic, Misaki is a clever student of the game, and you just don't walk into a tournament you have prepared for and looked forward to for ages without knowing such a basic fact.
