This should be taught at school so parents don't have to dig into their pockets every time. Personally if they do jobs at home they get pocket money. Some parents dish it out and then wonder why they can't afford things.
How many of them have agents? Do some negotiate with their parents? Do some negotiate by themselves.? . I presume agents only get involved when a player gets either a wage rise or moves to another club. Just interested how it all works.
