It does seem that most kids of players almost automatically get enrolled in the academy of the clubs they are at. So if they are getting the potential benefits of coaching from a very early age as well as potentially having an aptitude for the sport from just being around their parents as well they may have a slight head-start. I'm not sure any of these who are at Liverpool will ending being top quality players but they may still end up having decent careers. Much like their father's to be fair.
