togashi is right, how are you going to go pro if you lack the actual passion for winning, if they just see a doll that does what they want they will not evolve as a player (that guy that got to the adult team proves that, in just the minutes he had, he wasn't thinking about going pro but winning and be a part of the team)
it's great that Aoi noticed that.
also unlike Kuroda, Togashi shows appreciation for the team.
although there are a lot of forwards that are like him (is probably the reason why the coach of musashino allows a player like that in a teamplay focused team.)
this view of football in a manga series is really great. (giant killing being the best)
