@lisaisa ironically, Japan football are forced to play teamwork type of football because there's lack of individual skills in the first place.
Back to the manga, Akutsu's determination are still pretty shallow. Like, there's no explanation behind his behavior.
Also, there's no way he could have that ego on the pitch, since the defenders have to communicate with each other to forming the defense line. So I think that ego only applies outside the pitch, not in the actual football match (except if there's more context about him later on).
