Other mistake: The Musashi team are ready for the kick off. But the aerial view shows the teams in positions incompatible with the situation; not every player is in their own half, and even more noticeably, there are no players by the center mark, in fact nowhere near. (00:03:05)
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).
