HOYD and youth intake question

I will try to ask this question clearly, though it is a little complicated in my mind.

You hire a new HOYD after youth intake day.
The next season or 2 are youth intake players his, or the previous HOYD's? - since they enter your academy system YOUNG.

Because I upgraded my HOYD with Driven personality, and his first 2 classes have been filled with "unambitious" players. They are 15-16, so they may belong to the previous HOYD, and I won't see this guys players until year 3?


I am ready to fire this guy (Nick Cox ENGLAND, who is supposed to be pretty good), but I may be jumping the gun.

I have all the other bases covered as best as I can - Superb Youth facilities, Exceptional youth recruitment and junior coaching.
Scouts, coaches and other staff members - a lot of positive personalities, and the worse personality any of them have is "Balanced".

Thanks for any help or thoughts. I have read a lot of info on HOYD's and YI and this topic never came up in any of them.

Thanks for all the help guys... You are real gems.

Yes, any upgrade to facility or change in background staff which works with Youths; need some years to have an effect. Also, player personality is being changed according to average squad personality
