I can't name my source, but I have it on good authority that the director of football keeps stocking the squad with players that managers won't use.
I could get into a lot of trouble for posting this, but none of Bernard, Kean or Iwobi have been able to get a game under either Ancelotti or Silva, and there are even rumours that neither of the two reserve full-backs are being picked at a time where both senior players are injured.
Keep this under your hat please, mate. I've probably said too much.
Iwobi seems to get a lot of games under. Bernard not so much, but he's being picked.
I've read back your post history regarding this matter, all I can say is that I hope you/you're source is full of it. Would be really sad to have such Game of Thrones screenplay running behind closed doors.
As far as Carlo and Nkonkou/Gordon not playing, I've been following Carlo from 2003 AC Milan. He prefers experienced players. I can't remember when's the last time he promoted someone from youth teams. Sure, they get to play if they're extremely talented players with star potential brought in for a price tag, like Pato was. Or like Kaka was. But other than that, I think you guys are waiting for Godot when it comes to youth team promotion.
edit:
@Carlito which article on ToffeeWeb did you have in mind exactly?
