Other mistake: When the Shimada players listen to the pep talk from their number 10, their jerseys just go crazy; some have written "Shimada" on it, but some others "Shimad" and there's a guy with just "SHIMA" on it. (00:05:00)
Other mistake: Manabu loses his glasses; Sanae hits him with her flag, but the action is animated incorrectly, and he goes down without the pole connecting. (00:09:10)
Other mistake: When Nankatsu scores their third goal, several Shimada players (two during Morisaki's passage and then the keeper when he turns around to see the ball into the goal) sport jerseys with the wrong team name, "SIMADA", missing an H. (00:09:30)
Other mistake: The animation of the team laughing at Ryo's joke about scoring 10 goals is botched to the point of the players basically convulsing. (00:12:55)
Other mistake: If Meiwa scored already 10 goals the previous year (when the championship was won by Shuutetsu) it is hard to explain how nobody from Shuutetsu knew about Hyuga, since they were serious contenders. (00:13:40)
