Audio problem: To cheer the team, Manabu is banging a stick on a can...producing no sound whatsoever. (00:06:15)
Continuity mistake: Rain notwithstanding, Urabe's hair doubles in size at the beginning of the episode. (00:06:20)
Continuity mistake: Takasugi's eyes as he cheers his team up are drawn in a way different from any other episode (as in, they are open!). Moreover, his elbow is still visible at the edge of the frame when the camera moves to Ishizaki, so he kept the same awkward position for an inane amount of time for no reason. (00:06:25)
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)
Other mistake: Misaki gets past number 7 for the decisive goal with an obviously recycled shot from an earlier phase of the match. (00:09:05 - 00:15:40)
Continuity mistake: Misaki receives the ball from Taki, and dribbles 7 and 6. The number 6 on the Musashi players is written with a thin font that stands out for being totally different from the rest of the episode. (00:09:05)
Other mistake: While he waits for Tsubasa to lose the two defenders marking him, you can see that two Musashi players are coming at Misaki from behind. They are gone in the rest of the scene, to the point that he turns around and brings the ball back outside the area unchallenged. (00:09:20)
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)
Other mistake: When Tsubasa is staring at Urabe running in the distance, Urabe's hair is see-through in some shots and you can see the shape of his skull (or at least a glowing circular spot that appears in some frames only). (00:11:05)
Continuity mistake: The timekeeper is at his table under the rain. The panel is looking different compared to the other shots - look at the "2"s and their relative height. (00:12:05 - 00:13:00)
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)
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)
Continuity mistake: When Roberto and Tsubasa's mom look at the field after the 4-4 goal, the books (?) on top of the people behind them changed color. (00:20:40)
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)
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)
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)
