The Football Is My Best Friend - S1-E4
Continuity mistake: When Roberto and Natsuko Oozora are laughing after Tsubasa left, Roberto does not have the large dish in front of him, and he's leaning against the table with his left arm instead of the right. (00:05:40)
Continuity mistake: The Shimizu goalkeeper reacts to Tsubasa's shot in two different poses. In the second he also lost his gloves. (00:19:15)
Continuity mistake: The first time we see Tsubasa's old friend Yayoi, she's surrounded by different people in the opening shots, and a different new batch later again when she reveals her name. (00:15:25 - 00:19:40)
Other mistake: When the Shimada players listen to the pep talk from their number 10, their jerseys just go crazy; some have written "Shimada" on it, but some others "Shimad" and there's a guy with just "SHIMA" on it. (00:05:00)
Continuity mistake: While Roberto explains the strategy to his mom, Tsubasa is busy fending off 2 opponents. In the first shot though there are 4, two of them just disappeared and his teammate Urabe appears instead. (00:16:35)
Factual error: The goal kick after 0-2 in the Nankatsu-Shimada game is illegal, with a (nondescript) player shown kicking the ball forward to himself rather than passing. (00:16:20)
Continuity mistake: Takeshi Sawada leaves everyone on the left wing in the dust. He beats an opponent that from the ground says "He's incredible." The guy behind him got himself a pair of spectacles in between shots. (00:13:40)
Other mistake: Wakabayashi and Ishizaki are shown in this episode as the only 2 players on the bench. The team is formed by 15 players, there should be another 2 subs. (00:04:00)
No Easy Way - S1-E12
Continuity mistake: In the second qualifying match, Tsubasa advances towards the keeper from the first match (blue jersey) and scores against a new one (light beige jersey). (00:11:15)
No Easy Way - S1-E12
Continuity mistake: When Tsubasa first scores, the keeper has no gloves, when Tsubasa scores a second time the gloves go from blue with a dark red back to yellow, and when he seals his hat-trick, the keeper has white gloves with the back blue like his jersey and then yellow. (00:10:00)
No Easy Way - S1-E12
Continuity mistake: In the first shot, from distance, of the bench, you can spot Wakabayashi sitting with a grim look on his face. A closer shot that follows shows nobody on the bench. (00:03:45)
No Easy Way - S1-E12
Audio problem: At the beginning of their conversation outside the house, the Captain and Roberto's audio is off-synch with the mouth animation. (00:01:40)
Other mistake: Talentless footballer Ryo Ishizaki juggles the ball with his foot when he's chilling riverside in a way that not even the most skilled pro in the world could pull off, not unless the ball was tied to an elastic string. He's bouncing it in a diagonal pattern just moving his ankle and somehow the ball pushed forward gets back to his foot each time. (00:06:05)
Other mistake: Misaki reminds Ishizaki about the next phase of the selection for the team. When he replies, someone drew eyelids on them, but the same color of the white of his eye. (00:02:30)
The Football Is My Best Friend - S1-E4
Continuity mistake: Sanae beats with a stick the naysayer; the stick has a flag wrapped around it the first time, then the flag is gone. (00:15:00)
No Easy Way - S1-E12
Continuity mistake: In the shot when the Meiwa team is begging Hyuga to play with them, the M of their jersey is black and not yellow. (00:13:50)
Continuity mistake: Morisaki in this episode is wearing the number 12 jersey, but he started the previous episode with the number 1. (00:08:35)
Continuity mistake: When Kojiro Hyuga lands after a wuxia-like leap over the goal, Genzo is suddenly not wearing his gloves. (00:14:55)
No Easy Way - S1-E12
Character mistake: In the first shot of the interior of the stadium, the banner says "We ♥ Nankatu", instead of Nankatsu. (00:03:40)
The Football Is My Best Friend - S1-E4
Continuity mistake: During his night training with high schoolers, Genzo is randomly shown wearing his gloves or not. (00:10:45)
