Character mistake: The characters keep referring to this match as Jun Misugi's last, hoping he'll win it, but Meiwa is an opponent just as fierce as Nankatsu, so even if Misugi beat Tsubasa, he would need to play still one more match. It's Misugi's last only if he loses (as in fact happens, but they can't know that).
Audio problem: When Manabu shouts for the captain, his lips are not moving. (00:21:00)

Trivia: International versions change Roberto's message to his coach at San Paulo FC, adding for some reason that he met a girl he fell in love with. This girl is never referenced nor appears, since, well, she does not exist? Roberto mentions that he met Tsubasa instead, who he wants to bring to greatness. (00:12:40)
