Continuity mistake: Ishizaki misses his tackle on Misugi and knocks down the supporters instead. You can see that they fall into the playing field, inside the lines. Sanae sits on him. Though and the lines are gone. The pants of the rightmost bystander go from brown to blue, also. (00:17:55)
Continuity mistake: When the supporter with the scaly-looking green skirt shouts "Misugi-san!" after his lame kick-off, she is missing "JUN" from the shirt. (00:06:30)
Continuity mistake: The kids are chatting and dismissing the threat of a Hyuga-less Meiwa FC. In front of Teppei Kisugi there's a red sports bag and something like a burlap sack; the two items switch position with the camera angles. (00:07:15)
Continuity mistake: Misaki walks away from the penalty area trying to find an opening for Tsubasa. When he thinks "Tsubasa-kun" looking at him obstructed by two players, the logo on his chest changed proportions. (00:10:00)
Continuity mistake: The towels and umbrella of the supporters behind the Musashi bench change color in the reaction shot on Yayoi when the coach asks a benchwarmer to get ready. (00:05:20)
Continuity mistake: Urabe dodges Musashi's number 7 and passes to Taki, who tries to dribble number 8. Something is wrong in this sequence; 7 is written in white, and 8 in blue. (00:08:00)
Continuity mistake: Misugi's face during his careless last stride has a muddy look. One could think that he's turning blue because his heart is malfunctioning, and he's lacking oxygen. When Takasugi gives chase, he has a muddy face too in a shot as well. They are both clean later.
Other mistake: Wakabayashi is holding the ball left from Tsubasa's lame attempt. His hand is positioned differently on the ball between shots, as noticeable from the hexagons. In that shot, his hat also has the wrong name "WGNZO", missing an E. (00:20:25)
Other mistake: Twelve players are warming up before the match, but only one is wearing a keeper outfit - there are two. (00:19:25)
Continuity mistake: Genzo walks out of the hotel wearing gloves in the long shot, wearing what appear to be miscolored flesh-toned gloves in several shots, and bare hands in the close-up. (00:08:00)
Other mistake: With a sigh, Genzo has to admit that he can't do anything for Hyuga and waiting is the only option. For his last line, his hat says just "W Genz" and not "W Genzo." (00:06:40)
Continuity mistake: Misugi lies on the stretcher; the pillow changes shape and position between shots. (00:03:05)
Factual error: The whole "Did the referee blow his whistle because of the goal, or because the match is over" isn't possible; the referee blows his whistle three times for the end of the match, not just a single time. (However, it should be noted that technically it's a universally adopted convention but not a hard-coded rule). (00:05:50)
Other mistake: The Musashi team are ready for the kick off. But the aerial view shows the teams in positions incompatible with the situation; not every player is in their own half, and even more noticeably, there are no players by the center mark, in fact nowhere near. (00:03:05)
Continuity mistake: The Musashi players snarl angrily that they were SO close to winning. Misugi is on his knees in the grass, but in that shot the rain and wetness is gone. (00:20:50)
Continuity mistake: Tsubasa is cornered and decides to shoot the ball vertically and jump at it to catch it midair as it falls. When he jumps, his jersey lost the blue collar. (00:18:45)
Other mistake: Tsubasa gets the stray ball very close to the goal line. Regardless of that, the Musashi players surround him and there's a larger portion of field around them with no lines. (00:17:30)
