Character mistake: According to the tactical reading of Tsubasa's dad, Tsubasa's flaw is that he's not used to team play since he's just been playing with the ball on his own from a tender age. Just seconds before, Genzo made the comment that Tsubasa is a clever player that can read the passes of his opponents instantly. So he's both clueless about team play and an expert on it in the space of 30 seconds.
Character mistake: Tsubasa runs with the ball from kick-off, which is not allowed. The player who touches the ball first can't touch it again until another player passes it to him. (00:03:45)
