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: The Tachibana twins caught the ball at the end of the previous episode, but ball possession is for Nankatsu at the beginning of this one.
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.
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
Continuity mistake: Before the opening of the match, Jun Misugi's jersey has a yellow collar, instead of its standard white. (00:06:25)
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
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: 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.
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)
Continuity mistake: In an act of murderous unsportmanship, Nakanishi damages the pitch trying to smash Tsubasa's leg. The pitch is pristine in the next shot though. (00:09:10)
Continuity mistake: Wakashimazu (not yet revealed) is watching the end of the match on TV. His travel bag is on the right shoulder, as opposed to the previous episode, but gets back on the left side in the next shot. (00:10:00)
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)
Audio problem: In the Italian dub, starting with the match against Musashi FC ("Mambo FC"), Nankatsu's goalkeeper changes all of a sudden last name, from Alan Crocker to Alan Parker.
Encounters in Semi-Final - S2-E1
Revealing mistake: After scoring, the Hitachi team advances to try to secure the result. During the progression of their forwards, the background with a ferris wheel repeats itself, and there's even a small audio gap before the crowd cheers repeat in a loop. (00:03:00)
Encounters in Semi-Final - S2-E1
Continuity mistake: Moving constantly forward, Misugi and his teammates leave in the dust Hitachi's number 3, 4 and 5 at least three times. (00:04:20)
Encounters in Semi-Final - S2-E1
Continuity mistake: Misugi shoots The Equalizer, beating a goalkeeper that changes hairstyle between shots. (00:06:40)
Encounters in Semi-Final - S2-E1
Other mistake: At the end of the match that Misugi singlefootedly turns around for his team scoring 4 goals in 15 minutes, the TV commentator praises his skill dubbing him "Field prince." In his internal monologue, Hyuga takes exception...so he is responding to something spoken on TV and that he couldn't hear since he's on the pitch. (00:07:10)
Encounters in Semi-Final - S2-E1
Continuity mistake: With his insight, Misugi asks manager Yayoi if she talked about his situation with Tsubasa. She mentions that Tsubasa wants to turn pro. Misugi reacts with his mouth closed in one shot, wide open in the other. (00:09:45)
Encounters in Semi-Final - S2-E1
Other mistake: When Furano and Meiwa face each other before the kickoff, the goalkeepers wear the same jersey as the rest of the players. (00:13:05)
Encounters in Semi-Final - S2-E1
Continuity mistake: At the tactical meeting before the match, Misugi is wearing long beige pants in the opening shot, then all of a sudden the blue shorts of his normal uniform. (00:16:10)
