Continuity mistake: When the sushi chef insult the client on the phone, the one in front of him has been eating and wipes his mouth after the initial surprise. However, as the shot changes, he is watching intently the match. (00:07:00)
Continuity mistake: Meiwa's keeper during Tsubasa's 3-3 equalizer has the number 1 jersey, but in the previous episode he had number 17.
Continuity mistake: Nankatsu loses the ball after the 1-2 kick-off. Urabe is quick to chase the ball. He looks at his opponents to his left, but then in the next shot he's looking at them...to his right. (00:13:15)
Continuity mistake: Once Hyuga intercepts the ball, he has a stand-off with Tsubasa, who vows that he will not lose. During that shot, Tsubasa is missing the captain insignia. The band comes back right away at the cut. (00:09:40)
Continuity mistake: The referee hands Kisugi the ball for the free kick. Notice his white socks. As the camera pans out to show the tactical disposition for the free kick, the ref is sporting black socks. (00:09:15)
Audio problem: When the coach passes the ball to Tsubasa, his lips are badly out of synch with the phrase. (00:03:40)
The Youth National Championship - S1-E17
Continuity mistake: When Hyuga points at the sky to make his menacing speech, the ground is clay instead of grass. (00:21:50)
The Youth National Championship - S1-E17
Continuity mistake: The first time we see the alcoholic coach of Meiwa in a professional capacity he is sitting on the floor with a big sake bottle. The bottle is in a different spot in the next shot. (00:17:55)
The Youth National Championship - S1-E17
Continuity mistake: During the opening ceremony, the Furano team leads with Matsuyama carrying a flag, then another player, then the goalkeeper. Next shot and the flag is gone and a generic player replaces the keeper. (00:14:40)
The Youth National Championship - S1-E17
Continuity mistake: When Ishizaki is chased by the colossal Taichi Nakanishi, he yells for help; Tsubasa's jersey has the number with the wrong font and color (black and not blue). (00:12:40)
The Youth National Championship - S1-E17
Continuity mistake: The first time Ishizaki meets Nakanishi, he has a jersey with a big black number 1 on a plain yellow back. When he bumps into him for the second time, his jersey is yellow with a red upper back, and no number. (00:06:30 - 00:12:30)
The Youth National Championship - S1-E17
Character mistake: Matsuyama meets Misaki and asks him with surprise if he's part of the tournament too. But in the previous episode, Matsuyama was aware of that already and mentioned to the rest of the team that since they qualified, they would face him. (00:07:50)
Continuity mistake: Nanbu's keeper yells at two defenders to contrast Hyuuga. They menacingly advance...and they are never seen again, it's different defenders that Hyuuga will beat to score the 3-4 comeback goal. (00:14:10)
Continuity mistake: As the Nankatsu supporters try to rally after the initial disadvantage, the red-headed kid is to the far left, right, left of the group. (00:03:00)
Continuity mistake: The scoreboard at the beginning of the episode is different from the previous; Nankatsu is on the top row, it was the bottom row in 1-12. (00:02:40)
Audio problem: When the tryout team is heading back home led by the Nankatsu trio, their lines (even in the original Japanese version) do not match the mouth movement at all (Misaki's is animated to open randomly, and Tsubasa's moves too frequently). (00:20:40)
Continuity mistake: Hyuga loses his baseball cap early during the dribbling, but it's back at his feet when he's standing savouring his triumph over Genzo in the box. (00:15:50 - 00:18:30)
Revealing mistake: When the assistant coach blows the whistle to start the tryout match, coach Shiroyama blinks back into existence next to him during the same shot a second later. (00:14:00)
Continuity mistake: Genzo picks up his injury falling with other 3 players. Forgetting the clumsy fall not fitting someone of his caliber in an easy catch, they fall at the wrong angle, wrong position/distance from the goal, and in the close-up, the offender 's foot stomps Genzo's ankle almost perpendicularly from above, but it's an angle of impact incompatible with their fall. (00:11:05)
Continuity mistake: One of the players maimed by Hyuga holds his bleeding wound. In the next shot, there's no blood or tear on the sock anymore. (00:08:55)
