Continuity mistake: Ishizaki makes an upbeat comment about Morisaki's performance, but Manabu takes exception. During the exchange, one of the boys in the background has green pants that turn blue and green again. (00:05:30)
Continuity mistake: When the sushi chef insult the client on the phone, the one in front of him has been eating and wipes his mouth after the initial surprise. However, as the shot changes, he is watching intently the match. (00:07:00)
Other mistake: In the aerial view of the stadium that follows the intermission with the sushi chef and Genzo at his mansion, there are 23 players on the field. One is the referee, you might say. In that case, the view is missing the linesmen. (00:07:20)
Continuity mistake: Morisaki makes the interception before Meiwa's number 8. In the reaction shot with the coach and Ishizaki, all of a sudden behind them it's full of people with a rather conspicuous tan who were nowhere to be seen a moment before. (00:15:05)
Continuity mistake: Meiwa's keeper during Tsubasa's 3-3 equalizer has the number 1 jersey, but in the previous episode he had number 17.
Factual error: It's the first leg of a tournament between elementary school players, and people skip work to see it, the city streets are empty because everyone is home watching it (since it is televised, too!)... That just never happens. It is not a world different from our own where everything is based on the sport (like Pokemon).
