I guess it depends as well what targets Ange has been set. If you tell a manager part of his remit is to develop academy players then you have to allow him some latitude with regards results. If you tell him you want CL in his first season then you can't expect him to start blooding youngsters.
Ange has left himself slightly open here. He had choices of experienced average players versus youngsters and he chose the former. That was when he only had shallow squad depth with injuries and suspensions. I'm not just talking about starting eleven either. I'm talking about all the times he didn't turn to these young guys and give them their cameos.
Now you look at his squad depth
Venom, Porro, Emerson, Udogie, VDV, Romero, Dragusin, Biss, Bents, Sarr, Madds, Gio, Kulu, Solomon, BJ, Werner, Son, Richi
That's a clear 18 senior players who Ange would have no problem being on the pitch. No reason that by Feb they're not all available for selection either.
Whilst Sarr and Udogie aren't that old, Ange won't really get the youngster question mark off his back until he walks the talk with our own academy. Even to date, he's been more likely to give Veliz, a recent acquisition vs our own academy, a go.
Whilst the club wants CL, it is the EL or ECL that could enable that.
