The Verification Test - S1-E16
Continuity mistake: After dinner, Roberto wants to speak with Tsubasa's mother. In the very first shot she's wearing a pale green shirt (like Genzo), but in the rest of their conversation she is wearing pink. (00:15:20)
The Verification Test - S1-E16
Continuity mistake: Mrs. Ozora messed up the dinner. When she rages at the stove, her skirt is blue. It was red when the scene began. (00:02:10)
Other mistake: Wakabayashi throws the ball to his teammates leading to the hat-trick; the ball in that shot is of the wrong size, almost twice as big as Genzo's head. (00:18:50)
Continuity mistake: Four players charge Wakabayashi illegally...but only three walk away once the referee whistles. (00:12:30)
Continuity mistake: When Sanae knocks down again her friend's glasses, the red-headed supporter gets a quick dye job. (00:21:30)
Continuity mistake: Behind Sanae when she hears someone else calling for Tsubasa's name, there are two spectators with a distinct appearance; one has a brown sweater with The Letter "K", the other a green shirt and indigo pants. Neither is in sight in the wider angle, and then they magically turn into a pea green K sweater and a blue shirt. (00:14:50)
Other mistake: When Nankatsu scores their third goal, several Shimada players (two during Morisaki's passage and then the keeper when he turns around to see the ball into the goal) sport jerseys with the wrong team name, "SIMADA", missing an H. (00:09:30)
Continuity mistake: Morisaki parries a header from Shimada's number 8, but during the 'freeze' in action that highlights the dramatic save, a player kicking the ball is instead shown, and in the next shot we see a number 10 (with different hair from the usual number 10) in front of the goal. Morisaki is also back wearing a number 1 jersey. (00:08:00)
Continuity mistake: When Sanae gets mad because the teacher is cheering for Tsubasa just as she does, the people behind her change in close-up. (00:04:00)
Continuity mistake: Commenting on Izawa's goal with the coach, Roberto Hongo has for some reason a big afro; his hair is almost doubled in size. (00:06:10)
The Best Keeper of the Tournament - S1-E25
Other mistake: Nakanishi is giving orders from behind, where, according to the commentator, he has a clear view of all the players. We then have a quasi-POV shot, and due to the peculiar perspective choices of this anime, we can see that from Nakanishi's spot he sees basically nobody, since the players disappear past the horizon. (00:17:00)
The Best Keeper of the Tournament - S1-E25
Other mistake: When Nakanishi drops the football after his bold words to Tsubasa, the ball doubled in size. (00:08:40)
The Best Keeper of the Tournament - S1-E25
Audio problem: When Tsubasa incites everyone before the match, and they stop watching the Furano match to go play, their mouths don't move. (00:04:55)
The Best Keeper of the Tournament - S1-E25
Other mistake: In the first minutes, some events of the previous episode are repeated and certain lines (Misaki's first, about Furano) are different - Teppei Kisugi's group arrives earlier, too.
The Fight for the Final - S1-E24
Continuity mistake: In the final shot of the episode, Nakanishi has the same jersey as the other players. (00:22:25)
The Fight for the Final - S1-E24
Other mistake: When he dismounts from the back of the truck, the Nankatsu supporter in a yellow shirt has much more intense shade of yellow, and he is also taller. (00:20:50)
The Fight for the Final - S1-E24
Revealing mistake: Wrong perspective during the Sawada-Hyuga play makes the chasing player from Maebashi look like he's 1 foot tall. (00:18:30)
The Fight for the Final - S1-E24
Continuity mistake: Furano and Nankatsu promise to meet in the final. Ishizaki rubs the back of his own head and makes a gesture with his left hand, but in the next shot he's back in the same position as earlier; both hands on the table. (00:10:40)
The Fight for the Final - S1-E24
Continuity mistake: When Matsuyama calls Misaki, Mamoru Izawa in the blink of an eye goes from Misaki's right to his left. The guys behind Matsuyama seem to change color of their clothes/move around between shots too. (00:10:15)
Ryo Shoots an Own Goal - S1-E23
Continuity mistake: Misaki volleys the ball into the net; two adversaries were opposing him but have vanished once he scored. (00:18:45)
