From the starting academy, RLC and Baker are probably your only shoe-ins with enough PA to make your first team, and that will take a while.
Ake, Bamford, Omeruo, will be good enough to be backups and injury cover, but they shouldn't ever be good enough to crack your first team. Which actually saddens me, I think Bamford should have a higher PA especially.
Up your junior coaching and you'll get some good gens though. Free up some wages and budget by selling off a lot of those fringe "not quite" players - but I do recommend keeping a few of the names mentioned above, or names mentioned by others, if only for your struggle to keep enough HG players in the squad.
After season 1 get ready to unload a lot of the former loan players for similar reasons. Piazon, Traore, T. Hazard, may become decent squad players if you need those positions, but as above, mostly won't be Chelsea first team quality.
Piazon is another player I am disappointed with on his PA. But maybe I just got a **** scout job? I dunno.
