I've got a feeling those 5 players will be the substitutions for Shinsei Inazuma Japan, but also that their role will only become clear during the international stage.

That being said, would it be possible for Grandfather to actually be Kageyama's father? Because it's a possibility that has been circling in my head for quite a while, seeing as he's also one of the characters that fell into soccer-induced-despair and whose career "died" with him.
