Continuity mistake: When Tsubasa is staring at the soccer grounds sign, it is written with a different layout in different shots. (00:10:10)
Other mistake: Tsubasa's mom calls him because the movers' truck is leaving. He kicks the ball outside the window, and is downstairs to catch it, quite the impossible feat especially when you factor in that he kicked the ball with not much of a vertical trajectory, almost in a straight parabolic pattern out of the window, and meanwhile he also found time to wear and fasten his shoes. And it's not even played up as something strange. (00:03:00)
No Victory in Semi Final - S1-E21
Plot hole: The whole team went into the match, and the tournament, without knowing its rules. They all are totally surprised by the fact that the top 2 teams qualify from each group. Of course, that's quite impossible, especially since there are veterans in the team, Tsubasa is a football fanatic, Misaki is a clever student of the game, and you just don't walk into a tournament you have prepared for and looked forward to for ages without knowing such a basic fact.
No Victory in Semi Final - S1-E21
Continuity mistake: Misugi's goal happens with either a high ball that curves downward, or a ground-level ball that rises suddenly, depending on the camera angle. (00:20:10)
Continuity mistake: Roberto realises Hyuga's fright technique; as he does that, the person between himself and Mrs. Oozora is wearing a white shirt. Reaction shot on her, and it's a man in yellow that was in a different position earlier. (00:11:20)
Continuity mistake: When Tsubasa and Hyuga have their senseless head-to-head challenge, they have a low wall and a green hill and trees as background instead of the bleachers that were visible in the wider angles. (00:14:00)
The Verification Test - S1-E16
Other mistake: 15 players were picked for the team. Genzo is injured, 11 are playing. Three are MIA with no explanation. Morisaki has to parry 10 shots for every other player, he parries 100 total. Ryo Ishizaki though is still a substitute, so that would mean there's the unexplained absence of even one more team regular.
The Verification Test - S1-E16
Factual error: Judging by the x-ray of the leg, Genzo wouldn't even be walking without a cane, let alone play. His tibia is shattered. (00:07:20)
Continuity mistake: Under the rain, Sanae's hair turns wet in the space of a cut (dry when she's waving the flag, damp when she comments that they need just one more goal). (00:01:50)
Continuity mistake: Urabe is commenting on Musashi's number 9 being dangerous. There is a man behind Ishizaki, with glasses and a blue hat. He's shorter than the shortest in the kids' group, but later in a wider view he's quite tall. (00:15:15)
The Fight for the Final - S1-E24
Other mistake: At the end of the previous episode, Taki crossed for the corner, and the keeper punched the ball before Kisugi could head it. This episode shows that Taki crossed for Izawa instead.
No Victory in Semi Final - S1-E21
Continuity mistake: Hyuga is looking towards Tsubasa; there'd distance between Urabe and him, but in the next shot they are arm to arm. (00:15:25)
No Victory in Semi Final - S1-E21
Continuity mistake: In the first shot with Manabu cheering, he is the same height as his single-toothed friend. He is supposed to be shorter - just as he a couple of shots later. (00:03:40)
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)
The Youth National Championship - S1-E17
Continuity mistake: When the camera pans on the crowd for the first match, and we see for the first time Roberto Hongo and Tsubasa's mom, behind them there are 2 people wearing big glasses, and one guy behind Roberto is wearing a beige jacket. Closer angle, and just one person sports shades, plus Mr. Beige Jacket is wearing a powder blue suit. (00:20:25)
No Easy Way - S1-E12
Other mistake: The same play-by-play commentator covers both the Nankatsu and the Meika matches, happening simultaneously in two different areas of Japan (and with no television coverage...of course, who does live commentary on elementary school matches anyway?).
No Easy Way - S1-E12
Character mistake: Nankatsu is referred to as Nankatsu FC, but in the first result the name of the club is spelled Nankatsu (in kanji) S.C. (00:10:55 - 00:13:15)
Factual error: The world record for high jump from professional adult athletes is barely above 2 meters when we do not consider the Fosbury flop. An 11 years old kid here nonchalantly leaps over the goal net (which is around 2 meters, close to two and half if they use a professional one, slightly less for junior matches), from a big distance and landing on his feet on top of the bar...and it's just an effortless transition before he does the REALLY impressive stuff. These kids are not supposed to be superhuman. (00:14:50)
No Easy Way - S1-E12
Other mistake: Morisaki is the substitute keeper, but he has the number 1 jersey (See next episode for an explanation about this part being prolly a mere continuity error). He also did not appear in the tryouts or the previous matches. He is wearing the Nankatsu Elementary school jersey but it's supposed to be a different character from that keeper - incidentally, in the match against Shuutetsu that keeper did at least a great save, better than anything Morisaki is able to do in these early episodes.
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)
