Continuity mistake: When Ishizaki is helping Tsubasa to get the ball back, there's a reaction shot on Urabe. His only recognizable teammate is the hat guy, but his hat had the initials "OONN" in the previous episodes, and now the hat says "DONN." You can see the difference in this episode too when Ishizaki has a flashback of their match against Nishigaoka, the hat guy is the keeper. (00:17:00 - 00:18:25)
Continuity mistake: On his way to goal, Tsubasa realises that the Shuutetsu Trio is chasing him. That is already a pretty big comeback, but Teppei Kisugi tackles him coming from the front, even. (00:20:45)
Continuity mistake: Genzo parried Tsubasa's shot. When he waves to his teammates saying it's their chance, he is barehanded instead of wearing his keeper gloves. (00:05:30)
Continuity mistake: When Genzo tells Shingo Takasugi to let Tsubasa shoot, Takasugi's hair changes color in the next shot, from his grey-ish shade to pitch black. (00:04:55)
Continuity mistake: When Tsubasa advances from kick-off, we see beaver-toothed Taki and another nondescript player running towards him, but in the next shot the one he is dribbling is Mamoru Izawa. (00:04:10)
Continuity mistake: After conceding, Nankatsu moves forward on a kick-off. Tsubasa, Ryo Ishizaki and another nondescript player are the ones advancing, but the generic guy is quickly replaced by Okawa. (00:03:45)
Continuity mistake: Sanae's patchwork flag has its patches positioned differently since the previous episode. The red one is the closest to the pole instead of being in the bottom further corner. (00:03:25)
Continuity mistake: At the time of the injury, Ishizaki's sock in close-up is full white, blue-striped when he gets up. (00:19:30)
Other mistake: Supporters cheer Ishizaki when he is trying to break the birdcage tactic. One of the guys who screams at him though is wearing the "S" jersey Shuutetsu supporters wear. (00:17:55)
Other mistake: Tsubasa's diving header hits the post square in the front in close-up, but in the wide shot it rolls out for a goal kick to the right of the post. (00:09:20)
Other mistake: There were 3 defenders not taking part to the birdcage strategy, but Tsubasa does not have to beat any of them, except Takasugi who tries an American football tackle that would be penalized even by the very loose standards of the referees of this anime, and that happens as if he had to intercept him coming from behind; by every logic he should be in front of him. (00:20:55)
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.
Audio problem: Tsubasa passes the last defender and is one-to-one with Genzo, but the shoot is described as coming from midfield. (00:05:10)
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)
