No Easy Way - S1-E12
Character mistake: Nankatsu is referred to as Nankatsu FC, but in the first result the name of the club is spelled Nankatsu (in kanji) S.C. (00:10:55 - 00:13:15)
Factual error: Blanket statement for most of the series; 90% of the tackles and blocks shown in the anime would never fly in a real soccer match. Some are particularly outrageous and deserve separate mention, but in general everyone's defense is careless at best, and downright criminal at their worst. Take Kojiro Hyuga's introduction; his 'dribbling' involves shoving the opponent off and the challenges for the ball end up with the opponents bleeding and with torn socks. Any ref would stop this sort of 'play' right away.
Factual error: The world record for high jump from professional adult athletes is barely above 2 meters when we do not consider the Fosbury flop. An 11 years old kid here nonchalantly leaps over the goal net (which is around 2 meters, close to two and half if they use a professional one, slightly less for junior matches), from a big distance and landing on his feet on top of the bar...and it's just an effortless transition before he does the REALLY impressive stuff. These kids are not supposed to be superhuman. (00:14:50)
No Easy Way - S1-E12
Other mistake: Morisaki is the substitute keeper, but he has the number 1 jersey (See next episode for an explanation about this part being prolly a mere continuity error). He also did not appear in the tryouts or the previous matches. He is wearing the Nankatsu Elementary school jersey but it's supposed to be a different character from that keeper - incidentally, in the match against Shuutetsu that keeper did at least a great save, better than anything Morisaki is able to do in these early episodes.
Other mistake: There were 3 defenders not taking part to the birdcage strategy, but Tsubasa does not have to beat any of them, except Takasugi who tries an American football tackle that would be penalized even by the very loose standards of the referees of this anime, and that happens as if he had to intercept him coming from behind; by every logic he should be in front of him. (00:20:55)
Character mistake: According to the tactical reading of Tsubasa's dad, Tsubasa's flaw is that he's not used to team play since he's just been playing with the ball on his own from a tender age. Just seconds before, Genzo made the comment that Tsubasa is a clever player that can read the passes of his opponents instantly. So he's both clueless about team play and an expert on it in the space of 30 seconds.
Character mistake: The climactic football match takes place at 2 PM, but the French and Italian dubs have Roberto mention that he's anxious to see how Tsubasa ("Oliver") will play "tonight." (00:06:00)
Other mistake: Roberto meets Genzo at the shrine in the early morning, and Genzo is pumped up and ready to go to the match. In another scene, Roberto is at the stadium hanging out on his own, but Genzo still hasn't got to the stadium and will arrive only much later when the match is about to begin.
Other mistake: Eleven Nankatsu players run past the 4 Shuutetsu guys who are looking for Genzo. They all wear the team jersey, the keeper is missing. They have just players total, 10 plus the keeper, the extra player was never supposed to be there. (00:04:05)
The Football Is My Best Friend - S1-E4
Continuity mistake: In the shot from behind when Sanae watches Tsubasa and the others leave the last training, the redheaded cheerleader is the one directly behind her and not the rightmost one. (00:20:25)
The Football Is My Best Friend - S1-E4
Other mistake: Tsubasa is quicker and much more skilled than his friends with the ball and took off much earlier too, but they reach the crosswalk at the same time. (00:04:10)
The Football Is My Best Friend - S1-E4
Other mistake: When Roberto tells everyone that they should try to treat the ball like their friend (except when they kick it, arguably) one of the kids who react with puzzlement at this unusual statement is Tsubasa, but he is the one character who already does that ordinarily as established in previous episodes. (00:02:40)
Audio problem: Tsubasa passes the last defender and is one-to-one with Genzo, but the shoot is described as coming from midfield. (00:05:10)
Blocked Off - S1-E6
Factual error: Genzo concedes a corner. Look when the ball goes out of bounds; the corner flag is misplaced. (00:15:30)
Kick-Off for the Future - S1-E3
Audio problem: When Sanae tells everyone in the class to shut up, her mouth is closed before her sentence is over. (00:10:15)
Kick-Off for the Future - S1-E3
Continuity mistake: When Tsubasa goes past the gates of the Nankatsu Elementary School, there are different people in each shot. (00:08:20)
Continuity mistake: When the two aces compete for Roberto's centering kick, Tsubasa is on the outside, in front of Genzo, going parallel to him yet as they land he's on the opposite side. (00:09:00)
Other mistake: Tsubasa is talking to 'his friend' the football as he does keepie-uppies. He is normally animated pretty decently during that activity, except in the shot when he is telling his friend about Genzo's skills; he is keeping his torso completely immobile, moving just his thighs, which is just physically impossible. A few shots later his torso is still again but at least his thighs are not in frame (the ball is though, what could he possibly be using to juggle it up?). (00:06:10)
Continuity mistake: Tsubasa moves up the ditch with a diagonal strafing. He then answers Sanae's questions but suddenly on that same ditch, by his feet, Roberto Hongo is resting, sleeping. If he were sleeping on the other side of the road (as it seems when he gets up later) then the feet of the characters in that first shot were facing the wrong way. (00:08:50)
