Always Terrible Youth Intake

I'm currently in a long term save using a Tier 12 database where i took over my local Tier 10 team and 12 seasons or so on, I'm in the Premier League/European competition and my facilities are all top quality.

However, every season, without fail my Youth Intake is terrible, the worst rated it could possible be. I have achieved almost everything I want to in this save, and i'd like to start getting some good youngsters to bring into the team as an added challenge, but they're always terrible.

Is this a known 'thing' when using a customer db and taking such a small club up the leagues? Will I ever get a good intake? Is there anything I can do beyond keep upgrading facilities/network (which are currently maxed out)?

Would love to know if anyone has any tips or similar experience.

I also play in lower leagues in FM 26 Console and am trying to see if as one video said, improving the Head of Youth Development to "Working with Youth" as best as it can, would make a difference, it also seems the personality of the HOTYD could pass on to the intake coming each year.

I guess that is why SI gives option to purchase "Golden generation"
