Stupidity: Roberto Hongo is the center forward of the Brazil national team, and as we see from Tsubasa's poster/magazine, he did not alter his appearance except for wearing a fisherman hat sometimes. Despite being surrounded by football fanatics, he manages to keep a fairly low-key profile and it's totally not a big deal to have a top tier footballer hanging around the small prefecture.

Audio problem: At the beginning of their conversation outside the house, the Captain and Roberto's audio is off-synch with the mouth animation. (00:01:40)

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)
