Captain Tsubasa MEMORIES: Kore wa Nankatsu Sho vs Shuutetsu Sho Taikousen Toujitsu ni Okotta Hanashi

The story takes place just before the original Nankatsu vs Shutetsu match that took place at the beginning of Kids' Dream. As such, the story is considered part of the canon of the regular series, taking place between the events that occur in chapter 4 "The great responsibility of the football club" of the 1981 manga.
