Continuity mistake: In his first dribble, Tsubasa goes past 3 opponents, but there's just one behind him in the next shot. (00:06:50)
Audio problem: When the handball team captain is about to throw, the ball bounces making the sound it'd make if he were bouncing it indoors, not on a grass field. (00:13:40)
Other mistake: Only one of the keepers from Meiwa FC appears in the episode; Wakashimazu replaced another one who is nowhere to be seen.
Other mistake: Jun's parents can't see the kids by the goal, only their shadows, but they are positively unfazed when Tsubasa is celebrated loudly and dangerously acting as substitute for him (which is the reason why Tsubasa is replacing Jun in the celebration to begin with).
Continuity mistake: Rain notwithstanding, Urabe's hair doubles in size at the beginning of the episode. (00:06:20)
Other mistake: In the previous episode it was established that the final takes place the day after the semifinals. The kids went right away to the hospital and talked about the match against Musashi, wearing normal clothes, and had a night adventure searching the town left and right. In this episode another day passes by before the final.
Character mistake: In the Italian dub, Hyuga mentions the lesson he learned from "Julian Ross" (Jun Misugi). He never played against him or his team, and was even in a coma during their match. He meant "Philip Callahan" (Hikaru Matsuyama). (00:13:35)
Continuity mistake: When Roberto and Tsubasa's mom look at the field after the 4-4 goal, the books (?) on top of the people behind them changed color. (00:20:40)
Other mistake: When Tsubasa is staring at Urabe running in the distance, Urabe's hair is see-through in some shots and you can see the shape of his skull (or at least a glowing circular spot that appears in some frames only). (00:11:05)
Other mistake: When Misugi is on the ground in pain after Tsubasa's equalizer, one of the forwards is watching him, but the number 10 on his jersey is transparent. (00:09:25)
Tsubasa's Resurrection - S2-E8
Continuity mistake: After hitting the crossbar, Misugi turns around to look at Tsubasa, who eerily teleported meters away in a zone of the pitch far away from the one he was standing on earlier. (00:09:35)
Other mistake: After the lengthy recap of the previous episode, Misugi is facing Teppei Kisugi, but the football shrinks during their struggle, being at one point smaller than the 10-year old's foot. (00:03:20)
The Brave Fighters from the North - S2-E2
Other mistake: In the stands, Wakashimazu is witnessing the match wearing his team uniform, spoiling the surprise since he has not officially joined the team, and he was not wearing them previously, in fact he went into the crowd without them. (00:03:05)
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)
Continuity mistake: For his assist to Sanada (with Misugi playing diversion), Honma gets a nice one-time tan. (00:14:10)
I Can't Play - S2-E7
Audio problem: When Wakabayashi shows up to shout at Tsubasa, his mouth is not moving. (00:22:10)
Tsubasa's Resurrection - S2-E8
Character mistake: In the Italian dub, Wakabayashi tells the keeper that he's replacing him, as in a substitution, while he simply asks him to let him have the ball for a moment.
Tsubasa's Resurrection - S2-E8
Factual error: At cost of stating the obvious; nobody is allowed to enter the pitch on a whim from the stands, even going as far as hitting a player kicking the football at them, it's pitch invasion. Nobody says anything about it and the referee is mysteriously absent though.
I Can't Play - S2-E7
Character mistake: Tsubasa loses the ball botching the control with his chest, and the announcer says that Nankatsu is in danger, caught by surprise and need to pull back. As he says that, the images show 5 defenders perfectly placed in the penalty area and the team not off balance at all. (00:14:00)
