Character mistake: At the tryouts, Tsubasa's teacher approaches coach Shiroyama chatting with surprise about the fact that he is in charge of the new team. But the episode opened with her exactly addressing him as the coach of that team. (00:04:40 - 00:19:45)
Continuity mistake: When Roberto is talking with the Ozoras before a horde of little busybodies invades the kitchen, Kodai Ozora has his pipe in the mouth or in hand between shots. (00:16:30)
Continuity mistake: When Genzo flips through the magazines, the cover is colored wrong in the first shot, with the cover photo filled in pink even if they went through the trouble of drawing it. In other shots it is properly colored. (00:11:20)
Other mistake: The Nankatsu teacher just announced the tryouts, and everyone responded positively asking for more training. Before Sanae starts her choir, the teacher is exactly the same height as the 10 year old students, contrary to the rest. (00:09:30)
Character mistake: In the map of South America, the nation of Chile is misspelled as "CHLIE." (00:18:05)
Other mistake: When Ishizaki is unwrapping his leg from the bandages, he's wearing the football boot he is NOT wearing before and afterwards. (00:15:10)
Continuity mistake: Coach Mikami's sunglasses are pitch black during most scenes, but in his reaction shot to the news of Roberto Hongo's international retirement they are tan. (00:11:35)
Continuity mistake: When Roberto is looking at the team having a laugh with the still injured Ishizaki, there are 10 of them in the first shot with no keeper included and 10 including the keeper in the second. Both are wrong though, since Ryo has a substitute that is playing, so should be 11 players all along. Later in the episode when they run for the special training, it's 12 people, with Ishizaki still sidelined, but in the close-up of Roberto's foot you can see them run past, and it's 11 players. (00:07:05 - 00:10:10)
Continuity mistake: Ryo Ishizaki is wearing yellow boots at first, then blue boots when he's throwing balls to the training partners. (00:02:15)
Continuity mistake: During Roberto's team talk, the keeper is wearing an ordinary jersey at first, then the proper red one. (00:01:50)
Continuity mistake: When the coach of the new Nankatsu team approaches the teacher, she picks the sheet with the players list and her left arm is not shown. In the wider angle the arm is right at the bottom of the sheet. (00:05:10)
