Continuity mistake: Ishizaki misses his tackle on Misugi and knocks down the supporters instead. You can see that they fall into the playing field, inside the lines. Sanae sits on him. Though and the lines are gone. The pants of the rightmost bystander go from brown to blue, also. (00:17:55)
Continuity mistake: When the supporter with the scaly-looking green skirt shouts "Misugi-san!" after his lame kick-off, she is missing "JUN" from the shirt. (00:06:30)
Continuity mistake: The towels and umbrella of the supporters behind the Musashi bench change color in the reaction shot on Yayoi when the coach asks a benchwarmer to get ready. (00:05:20)
Continuity mistake: Misugi's face during his careless last stride has a muddy look. One could think that he's turning blue because his heart is malfunctioning, and he's lacking oxygen. When Takasugi gives chase, he has a muddy face too in a shot as well. They are both clean later.
Continuity mistake: During the dramatic post-goal phases, there are two players right by the ghost of Misugi in the aerial shot, but just Tsubasa in the closer angles. (00:21:10)
Continuity mistake: Misugi, half-blind from the strain, scores. Manabu sports at his neck the whistle that was missing earlier. (00:20:55)
Continuity mistake: The teams resume playing after Misugi came clean about his illness. When the camera pans to the crowd, there's nobody behind the table with Misugi's parents. (00:12:55)
Continuity mistake: When the game starts again after Tsubasa's goal, Manabu is holding a can he uses as a drum, but it changed color (from metallic to red) since the previous episode. Besides, it was a can of soda, not a tin with a (dangerous!) jagged lid that required a can opener. In the next episode is back being a metallic beverage can. (00:06:30)
Continuity mistake: Camera on Jun's parents; the crowd behind their table in the wide shot is different (other clothes, colors etc) compared to the close-up. (00:04:45)
