Believe you can in classic but not the full game. If you get the editor you can change the name of the youth intake players and make them your son.
You can actually make it say that. Just have to go to the right screen and your manager and the would be son.
I've done it, when I get home I'll try to post screenshots if y'all want.
Yep. Not just father/son either. You can add change or remove any relationship in the game, and the reason for that relationship.You mean like edit a father and son?
